This video shows how I take microwave magnets out of a microwave.
I hang screwdrivers, pliers, saw blades, etc on them. I hold up maps, building plans, instructions, etc...with them. I pick up nails, screws etc... with them..... the list goes on.. AND here's another cool thing I do with them:

Our microwave quit working several years ago and while at a local hardware store I asked if they carried microwaves because ours had died. He asked if I had checked the fuse in the microwave. I told him I didn't realize there was one. He proceeded to show me replacement cartridge fuses and told me they are immediately inside the microwave where the power cord enters. I went home and tried to take the outer cabinet screws out and discovered they are security torx, a torx fitting with a protruding pin in the middle, something I didn't have, so I used a dremel to cut a groove for a slotted screwdriver. Found the fuse and used a multi-meter, and found no continuity. Went to the hardware store, bought a new fuse for less than 3 bucks, put it in buttoned everything up and the microwave worked like a new one. Makes me wonder how many "junk" microwaves only need a new fuse.
That's a great tip, my friend! Thanks for posting!
Awesome! I've received a microwave with that exact problem. There are so many electronic devices in our junkyards with such simple to fix failures, it's awful. So often it's the fuse or the filter caps.
There are a lot of things in the junkyard that could have been fixed. Sometimes I wish we could all get a little taste of the Great Depression. I think 1 year of it would be the best dose.
Virgil Caine is my name The torx with a pin in the middle is an easy fix. use a small screwdriver or sturdy knife tip and break the pin off!
You stole my idea ! Dremel is awesome. I don't know how many things I use it for. Just bought some tint diamond drill bits for it. I drill through small flat round stones and glass pendants with water., for the lanyard hole . I etch tiny things in the rocks too. Birds, ships, etc.. They make great gifts !
It's amazing what you can find on youtube at 3am when you can't sleep!
Good vid, enjoyed it 👍
Sorry you can't sleep. If you want to go to sleep, watch my extremely lame video on how to make punch: czcams.com/video/VVhFBWl2BV4/video.html
It's so boring, it will put you in a coma!
Haha, interesting video but you are not missing anything if you fall back to sleep. My favorite kind.
I appreciate your time and efforts to share this with us. Thank you.
You're welcome! thanks for the nice comment!
One of the best tutorials ever, super straight forward and great voiceover! I was able to follow along perfectly and got it out with ease, 10/10 thanks for the video!!
so glad you liked my video. Thanks for taking the time to watch and comment, kit
This video is much appreciated. Well presented with good info. We have recycle electronic bins...I picked up a discarded microwave and kept myself entertained for the evening. I'm 'older'. Turn the clock back 40 years and people salvaged 'everything' for screws, brackets, wiring, etc. I miss those 'get our hands dirty ' days. Yes, those were the folks who got us to the Moon.
yes! I have 2 big boxes in my shop that's labeled "CHOP". like "chop shop".... I throw hardware and other useful items in this boxes that I chop from old junk before I discard.
Hey Phil, just a word on safety. On the Capacitors: ALWAYS discharge a capacitor BEFORE starting work on any circuit. Don't cut any wires, loosen any screws, or poke around with fingers or instruments. Discharging with the screwdriver method is an acceptable way for these capacitors. Some, not these, can hold so much power that they can melt screwdriver blades! (Those have to be discharged through a resistor) The last thing on the safety checklist: Safety glasses! You never know if or when the tube might shatter. Wrestling the bracket off, or prying the magnets out could shatter the tube. Some are cracked already which is why the unit failed. Some tubes are glass, some ceramic, some have a metal shield, some do not. The 'don't inhale' thing, is that a small percentage of the 1200 watt and larger type have a small amount of Mercury Vapor in them, and the whole range of sizes can sometimes contain Americium. (Just like your smoke detectors do- really, look on the back, there's a label telling you so!
AGAIN ALWAYS DISCHARGE CAPACITORS BEFORE DOING ANYTHING ELSE!!!!!
John, I always appreciate helpful and intelligent comments! Thanks!
Thank you for this video! I have several old microwaves and had no clue they had magnets in them. I could use the magnets to make something to pick up rod stubs, metal shards, ....in my weld Bay! This is a huge help to me! Thank you very much!
Glad I could help! Thanks for taking the time to comment, Sean!
Excellent video, I love seeing how things work and I'm glad I watched it, you spoke so clear and gave good caution...liked your ideas, reasons for getting magnets and links on your description. Thank you!
You're welcome! Thanks for watching!
Great video, thanks. I've recently begun taking the tiny rare earth magnets out of broken ear buds. I don't have any projects for them yet, but they're on the fridge when I need them. 🙂
8 years later and still responding to everyone's comments!! Kudos to you good sir 👏! You are getting a like and subscribe just for that!
Excellent, DrewG!!!! I really appreciate you! I hope you find my other videos just as useful!
Phil I want you to know that after first watching your vid a couple months back, yesterday I finally dismantled and salvaged the magnetron out of a big old microwave i'd been planning to.. so cheers :-)
-and reading your comments section is a joyful inspiration - I very much appreciate your enlightened attitude - thanks again mate :-D
Glad I could help, BD! Thanks for watching and commenting, my friend!
Great video. I very much enjoyed it. I especially liked how you gently removed the taps using the channel locks.
Glad it was helpful!
2:40, that copper coil makes a great addition to any tool box. The wire comes in handy for lotsa things at the strangest times. Also, the older microwaves (don't know abt the newer ones) had great little squirrel cage fans that u can take out, wire up and run on house current.
Great tips!
I installed one in bathroom. As a vent fan.works well
There is also a good hunk of pure copper inside the magnatron as well
The motors are also good to have, and the transformers...there is alot of neat stuff you can get electronics wise out of a microwave
indeed
done this myself before this video, magnets are great for lots of uses, holding while welding, magnetising tools etc. good vid
YES! Love these to hold metal together while welding. Thanks for taking the time to comment, Gram Wat!
Thankyou for making a thoughtful how-to video.
You’re welcome! Thanks for the kind comment!
Back in 1971 I needed to install a new part in our TV and when I took the back off and reached in to remove the old part I touched the capacitor and let me tell you I'm 71 years old now and I still remember how bad that thing shocked me ! I had no idea it held power after I unplugged it so take warning when he said don't touch it !!
AMEN, my brother!
HA!
You're a smart man!!!
Indrid Cold: a potentially lethal game you used to play. he should have just destroyed you anyway but i suppose you are a quick learner so it worked out ok or so i am told
BTW: back in 1971.......... i was negative one year in age.
I know this is an older video but I am grateful for the information. Thanks for a no nonsense account of removing the magnets. If I neglected to discharge the capacitor, it could turn out differently!!
Cheers
Thanks for watching an commenting, Robert!
I love the way you applied safety means in removing the magnet. Just like active energy, we don't play with safety. Thanks for sharing
Glad you liked my video, Active Energy!
Amazing that you still reply 11 years on 👏 I have missed out on magnets on 3 or 4 microwaves so will be sure to try next time, thank you
I have been replying all these years because I love my subscribers. Glad I could help you out even if you don't subscribe. Hope my other videos will help you out as well
Thanks Phil. Very informative. We shouldn't be wasting anything. Reuse everything we can.
Peace.
agree!
I have dismantled several microwaves for the magnets. They are super strong and can pinch your fingers to the point of a blood blister. I use the magnets for various things, like gripping a dust collector vent on the lathe ways, one on the side of the drill press to hold the chuck key, and so on. Fortunately, I knew about capacitors.
indeed those magnets are nice!
Garth sheane thank you you answer my question and I'm sure there may be more uses for them
There's something about magnets that has always fascinated me. The way they work seems almost like magic.
Me too! I think most people are fascinated by them. The amount of views I got on this video kind of shows that. Thanks for taking the time to comment, my friend!
almost like magnet
Now you're talkin! There's something delightful about invisible forces, especially those that seem to defy the invisible force of gravity.
Its magicnetic
Good information, especially about the capacitor (though I've known their capabilities for awhile, they still make me nervous: that is a BIG capacitor). Ironic that I found this video about a week after I had a microwave quit, but now I have a use for it. Thanks.
ya... these microwaves don't last very long. I've been through 2 in the last 5 years. worse than computers. We quit buying the high-end ones, because they don't last any longer.
@@PhilCrockett I have an above range maytag. It was in the house when I moved in in 1997 still works.
My Dad taught me to always take apart any broken elec device just in case you can get it to work. My last microwave I did cut the cord and kept. Then took out the screws and put them in the screw bin. But I stopped then and tossed the microwave.
Will have to go further next time.
Good stuff thanks!
I've been told there are plenty of things to keep and/or salvage in a microwave. I keep getting some interesting tips from people. Thanks for the feedback, Jerry!
Thx , now I have learned something new. Never knew where those
round,super ,strong magnets came from until now .
Excellent! Thanks for taking the time to comment, Marsias!
Speakers are also a good source of magnets.
But they are brittle and can break if dropped, hit, eyc. They are strong-ish, but not as powerful as rare earth magnets used, for example, in disk drives. Some brick-sized ones can't be removed from sheet steel without tools.
Thank you for the information and now I can start a collection.
U will find that u use them for everything!
@@PhilCrockett I am finding that out here on CZcams. I want to try and open up a lock using them and other uses. Thanks for the reply
Thanks for the vid. never thought about the magnets in a microwave. Using the old microwave to store welding rods with the light on only. Very humid here. Just cut up two speakers up for the magnets. I use them to hold screws when I dissemble small subject matter. I have them every where. These magnets look very clean. Thanks again
Glad you liked my video. I can’t seem to get enough magnets! Very useful!
Some people are attracted to magnets, others are repulsed. There are both positive and negative comments on the subject. Then there are electromagnets, but I don't know the current thinking on them. Seems like people are poles apart on the topic!
Alan from Brooklyn
Very well said !
Alan from Brooklyn
It seems that the magnet business is picking up.
LOL!
U punny
Electricity, Gravity and Magnetism are different expressions of the same energy field
I first took apart a magnetron 55 years ago. It was a take out from a post ww2 radar unit. What I got out of it were two HUGE alnico magnets in aluminum jackets. Taking things apart is a great way to learn.

Yytyyyyyyyy
Bob Pendleton gfgggggguy
Yeah I've learned I'm no good at putting things back together, "A man's got to know his limitations" Dirty Harry Calaghan.
Yes, yes and yes. There's nothing like taking things apart--plus it's fun.
Cool video phil, not only was it educational and entertaining cuz i learned something new, i also laughed my ass off reading your replies to peoples comments, you're a pretty funny dude, keep up the good work!!
Glad you like my vid and the comic relief!
Thank's big guy I really appreciate the information and I hope you will keep doing cool stuff like this. I'm glad I found your channel and yes I did subscribe so please keep up the great work and I'll keep coming back for more and sharing your video's with as many people as I possibly can.👍💯👍
Thank you soooo very much, Randall!!!!!

Shorting a large capacitor with screwdrivers can cause it to explode. You should use a circuit with a resistor and let the energy be converted to heat. Do not touch the resistor, as it may be quite hot.
thanks for the tip, Bryan.
I love Alnico magnets "vintage speakers" ..these Mud magnets are cheap - but did learn a microwave has magnets i never knew about, so thanks i guess.. Might come in handy building my DIY 50" speaker from "back to the future" eh
Sounds reasonable to me!
Thanks for the video Phil. I have a question about the magnets, Are they hard and stable, Or are they brittle and chip/break easily?
they are hard, but will break if dropped.
What an educated video ! Now if you can talk about some of the uses that we can do with magnets and the transformer and any other parts from that microwave would be absolutely awesome ! Thank yo so much ! It was very educational !
Indeed, my friend! I give some examples in the video description as well as some links. Thanks for taking the time to comment!
@@PhilCrockett I made a couple of comment below toward some haters you should enjoy laughing about ! Thanks
I enjoyed ur comments. Just make sure the language is kept rated G. I try to keep a channel that kids can look at. Plus..... I’m ‘old fashion’. Thanks for having my back, my friend
I liked the "to remove the door we bent it backwards until it snapped and it come rite off" lol
YES!
Great video @PhilCrockett - most people don't realise what an incredible piece of technology that have in their homes: the magnetron. The story of its invention is interesting too, almost accidentally designed to get over a patent relating to triodes (a cathode/anode set up with a 3rd variable voltage in the middle) owned by Western Electric. People couldn't copy this invention, so they started using magnets to influence the flow of current through the triode to get around the patent. Then they discovered at a certain magnet strength, the contraption emitted microwaves (small waves) that could be used heat up water in food. And...your microwave oven has spinning turntable to avoid standing waves, that's why it's there!
Microwaves are FULL of FUN things
I use a magnet to keep all the small drillbits safe
Small bit such as 1 mm is easy to loose and a magnet on the table or against the wall helps when you have to change bits when working on a project and you have to drill different size holes.
great tip!
same here, and to keep tiny screws from walking away on my workbench when working on electronics
wish i kept my convection MW. Just tossed it last month, it died after16yrs. Always liked magnets for science projects and amazed at how powerful they can be, especially Neodymium ones.
Indeed!
I just took one out of a microwave and was going to continue to take apart the housing around the magnet and my husband put it out in the trash. I am so livid! These magnets are strong and great in securing things in the car's vehicle trunk.
Don't be mad at your husband....... he loves you!
LOL
I remember a friend of mine's big brother removing a small capacitor from a distributor and handing it to me when I was a kid. Of course he made sure I got a hold of the wire and the housing. POW! And that's how I learned about capacitors.
Finally it's Ed Yea, that’s back when we were kids - just being kids! These days most kids would be “traumatized”!
Capacitors are fun! 😉
LOL, I'm still traumatized. That's why I'm on CZcams. It calms me down. Wait... maybe I'm just old, that's what calms me down. Dang it.
I was watching a friend in a TV shop work on a TV. He reached up and laid a charged high voltage capacitor on the foam pad on the TV I was leaning on and of course I picked it up. The laughter was tempered by the fact that it barely missed a picture tube when I threw it across the room.
ziznf!
I have taken magnets off speakers radios dryers and washing machines , fans, televisions but not microwaves, but know I have a good conceptualization on how to get the magnets from a microwave. Thank you
You're welcome, Fernando! Thanks for the comment!
That pink at the top is a ceramic insulator that is made from beryllium oxide. If you break it or chip it and breath the dust you could get berylliosis, an incurable disease of the lungs. The first thing you should have done is wrap that pink insulator with electrical tape.
lol! I get that comment a lot. I've done my research on this....... it's just like asbestos and popcorn lung. lol. Thanks for watching, and commenting.
Microwave capacitors usually have a bleed resistor built in. I've never come across one that holds its charge for more than a few minutes. But it's best to short it just in case.
yes indeed
When you showed shorting the capacitor with two screwdrivers, you didn't stress keeping your hands insulated from the screwdriver shafts. That section of your video only showed the bottoms of the shafts - the handles weren't visible.
BTW, what do you do with the magnets? Compared with neodymium magnets, they're not very strong. What are they useful for?
Some things I shouldn't have to explain in detail. As far as what I use them for.......
I hang screwdrivers, pliers, saw blades, etc on them. I hold up maps, building plans, instructions, etc...with them. I pick up nails, screws etc... with them..... the list goes on.. AND here's another cool thing I do with them:

not to mention, you can ruin two good screw drivers that way. many years ago, in shop class in the 70's, our teacher charged a 45 uf 600 volt cap to 400 volts, with one of the power supplies we were using in the classroom. he blew his perfectly good old timer 3 blade apart, showing us the dangers of capacitors. he was heartbroken over that knife. he talked for weeks about how he missed that knife. i, myself, have tossed screwdrivers away after doing stupid things like that, testing for power. in most appliances today, including air conditioners, the caps discharge themselves within the circuit. i haven't found a live cap in over twenty five years of air conditioning and appliance service.
Same here Randy, there is usually a bleed resistor. ("A little bleeder" as my Dad used to call me!)
What are they useful for? Of what use is a newborn baby
As one who is curious about microwave ‘guts’, but have never taken one apart, thanks for the adventure/tour. It makes me want to research how a ‘magnetron’ works.
No prob, Rick!
Ik ben totaal geen elektricien dus dat van die stroom schok snap ik niet. Maar ik wil wel die magneten hebben . Als ik nu die magnetron in een bak water doe (en dus een kortsluiting maak (denk ik ) ) Is het gevaar dan weg ??
De condensator kan in een emmer water worden neergezet. Ik zou echter niet naar die problemen gaan. Ik zou het gewoon helemaal niet aan, en het komt goed.
Good video, but it should come with another warning....The little pink, sometimes white ceramic ring around the end of the antenna, the part that points toward the micro wave cabinet or cavity, can be deadly, if shattered and the dust inhaled....No treatment can help once it's in your lungs...Just a heads up.
While beryllium oxide used in the magnetron is safe in solid form, it's dangerous in powder form and inhaled which can cause berylliosis. So don't grind the beryllium oxide ceramic insulator and snort it, snort coke instead it's much safer. lol
YES! this has been an on-going exhausted topic over the years in this comment section.
@@PhilCrockett It's exhausted once the last comment is made about it ;-)
I have taken apart many microwaves for the components, and all capacitors I have encountered have a bleeder resistor attached to drain off any charge from the capacitor.
That's good to know!
Another source of magnets is hard disk drives. These Neodymium magnets powerful. You don't want your finger between two of them. They have a mounting plate with tiny holes. So have them around the basement to hand stuff. You can buy these buy the pound online, BTW.
You're in luck! I have a video on that!
czcams.com/video/YKzPt18aE_0/video.html
Very informative and thanks for letting people know about tha capacitor
Im VERY afraid of electricity. I grabbed two power lines in 78. Didnt know they were live. Got hit with 480 volts for bout 8 sconds. Put me in the hospital for 3 months. Lost. My ring finger on my left hand. So thank u sooo much for the great info.
And yes folks. The magnets
R really strong. If u drop a box of nails. Its a great way to pick them up
Sorry to hear about your bad experience. I worked for years in the Burn ICU at a local hospital, and I saw some pretty bad things that happened to linesmen. Glad to still have you around. God bless you, my friend.
Fine job mate - pay no mind to the naysayers and dislikes! .. Hell, magnets are just handy to have and fun to play around with - where or what would this planet be without magnetism - y’all think about it.
Yes indeed!
You are okay my friend. Your skills should not go to waste.
There are a good number of mean ones who either die with their knowledge or make hateful comments. Your post is titled taking magnets out of a microwave, why watch and then whine?
I need some magnets. I was wondering where I could get some easily. I so happen to have a microwave that stopped working. Your post was very helpful. Thank you
HA! YES! I always wonder why people seem surprised by what they are seeing when they click on my completely and totally honest title. I have a video on How to Fillet a Bass.... I get sooooo much hate mail on that. They're like..: "Can't believe you did that!" and.... you shouldn't kill bass!"...... and yet...... they clicked on it with both eyes wide open. Anyway...... hope you get a chance to see my bass video too... Thanks for the great comment and laugh! You are my kind of friend, Gye Boor!
I like to put my glass on a magnet from a magnetron with an AUTISM AWARENESS wristband since i was born in April
Thank you for your tutorial
Glad you like my video, Linda!!! Thanks for taking the time to comment!
It’s not just the magnets, it’s the transformer capacitor and diode that I like as well! Btw The magnetron tube by its self without the fins and the magnets gone looks really pretty!!!
Yes... I get a lot of comments like yours. I wish I could see a video on the use of the other parts.
What a joy to see a craftsman at work
Hahahaha! Yes! I’m a true craftsman!
capacitors can actually build up charge from just sitting there, not sure how, maybe some kind of chemical action inside that separates charge or just static in air currents can slowly add static charge that the device stores up. Most high voltage capacitors in microwaves have a large value resistor between the two capacitor terminals that will slowly discharge a charged capacitor. If you have high voltage insulated screwdrivers, you can clip say a 10 megaohm resistor between the two screwdrivers and use this to contact the capacitor terminals and this will discharge the capacitor in about 30-60 seconds. Most people do not have a high voltage test meter (2000 volts) to measure if the capacitor has a charge on it, so making sure to do a discharge and then clipping a shorting wire across the capacitor to make sure it doesn't build a charge again is a good way to make safe this device.
Also the ceramic portion of the magnetron antenna that sticks out of the device has beryllium oxide just under the the ceramic surface. DO NOT break or scratch this ceramic or this toxic dust can get airborne and cause nasty bodily pain and distress that can't be reversed.
Best to research this because there is a lot of myths.
Shalom Aleichem.
Please excuse my ignorance, but how would a capacitor get recharged after being removed and discharged?
I've been scrapping Microwaves for year's an as a retired mechanic I know how dangerous capacitors an other electrical equipment can be if not handled properly. I didn't realize a capacitor (or did I read it wrong) can recharge itself?
I have multimeters that go up to 2,000vts and beyond because I worked on large boat's with high power shore power an one doesn't wanna make a foolish mistake while in a bilge with saltwater in it or any water for that matter.
Thank you in advance.

Just purchased some magnets for a project. Good video.
Thanks, Derrick!
This is a great video, even now. I'm still taking them apart the same way as you did a decade ago.
Right on!
Sorry if this has already been said but let's not forget that there's actually three magnets, not two, inside of a microwave. Don't forget about the neodymium magnet inside the turntable motor. it's tiny but mighty 😜
Thanks for the tip, James!
You've turned something interesting into a painstakingly slow vid with freeze frames and all !!
YES! I agree. This is one of my old videos back before I had good software and experience. Thanks for your professional critique. I will have to check your channel out for some pointers. Thanks, G4R!
G4R
trolling 5 year old vids ?
LOL
Phil, I also enjoy salvaging items which can be used elsewhere, but my question is how powerful are these magnets?
Are they similar to the 'super-magnets' one would find in a computer or basically more or less what you'd expect from a 'standard' every day magnet?
These are not rare earth magnets, however...... they WILL pinch the heck out of your fingers! I get this question a lot... I've never tested the strength. Maybe I should do a video on that.
What's the avg. gauss measurement on the magnets?
Makes one heck of a refrigerator magnet. Ones you pay for in a store barley keeps a reminder-note on before sliding off. Wonder any good use the glass doors have? Better R-value for my basement bay windows.
You understand! thanks for commenting, Recco Con!
I laughed so much my wife called the mental asylum. I am sure I saw this guy in the ward next to me hahahahah
Was that you next to me with the boot on your head?
@@PhilCrockett 🤣🤣🤣🤣🤣
Better make sure that capacitor is TOTALLY discharged before you touch any of the high tension side of the circuit. Being an ex commercial microwave/induction engineer one of the first things you are told at the Panasonic training seminar is that capacitor will hold 2500 volts at 10 amps. Thats not a 'ouch that hurts'... thats a 'he was thrown across the room and then his heart stopped, and thats why he is now 6ft under. Rest in peace'. Its a killer. The bleed diode is supposed to remove the charge in the capacitor over a period of time (in this case the black package on the right terminal to chassis), but they can go open circuit and the capacitor remains charged. As a side note, a fuse NEVER blows in a microwave for no reason, it is usually lazy door switches/mech. Never 'just' replace a fuse.
great comment, Jason!
I'm thinking about them as clamps for guitar repair. It might just work in certain situations thanks phil
interesting application for sure. Let me know if it works!
These magnets are awesome. I randomly found one that I used for sorting scrap until I lost it. They are powerful. I'm too scared to take a microwave apart and currently without a magnet so might have to buy one
I've taken many m/w's apart over the years. as long as you don't mess with the capacitor, you should be alright. The rest of it isn't as bad as people say. THere's a lot of bull being said about the risks. but....... buying them is always easy, and they are fairly cheap.
Phil Crockett - Thank you for that info. So can the magnet be removed without removing the capacitor?
Transformer is very easy to rewire to different use.
You can easy get good amps for bigger battery charger or car subwoofer amplifier in home usage. I have build my own 400watts using car amplifier and I build in power supply using rewired microwave transformer which gave me over 30 amps.
My car battery gave up after playing 30 minutes of havy techno.😃
wish I knew how to do that. Make a vid, and I'll watch!
one of the best magnets I have recycled came from a computer hard drive, also from the magnetic emergency trailer lights.
Love those hard drive magnets!
I have lots of old hard drive magnets. I wish they were not the shape they are but they are very strong neodymium magnets. Some analogue televisions have large nickel-iron magnets and stick diodes. But more importantly, large capacitors. Sony has extremely good capacitors in their old analogue televisions. Old analogue home stereo units have excellent transformers and even the zener diode to regulate the lowered voltage to 12 volts. Old AM only transistor radios have germanium diodes, transistors, and variable capacitors. After the fall of Radio Shack, I am constantly salvaging components. I know these components can be purchased from online stores. But when you need a 10 : 1 transformer for a powersupply immediately, a full wave bridge for the same power supply, or inductors for a homemade tank circuit for a resonator circuit, there may not be time to wait for a slow online shipment. The salvaged resistors, capacitors, inductors, schottky diodes, and such are always there. The salvage operations are going on constantly. When I find dead electronics, I take them home for processing.
Great video...I was getting ready to buy some magnets...now I won't have to. Thanks
Thanks for the positive feedback, Hop'n!
I use magnets from larger loudspeaker elements. Good to find screws and can also be used on a screwdriver.
I love magnetizing the tips of my screwdrivers. Great use!
Thanks for the revelation that a broken & crappy microwave has a couple of pretty powerful magnets Phil. As soon as I seen this I dug our last broken oven out of the basement. Ripped the thing apart with a Philips screwdriver, snips and a flat headed screwy! Took me all of 10 minutes ! These kinda magnets aren't that easy to buy in a hardware store in the U.K. Maybe online but a what strength & prices!?!?
What puts people off, especially if they're gonna be used to make money (hard to come by in this now shit world) & guess what they will be used for....? ! ? ! lol.Will try em out & tell the shop owner's how easy it was to remove their alarm tags. so they'll update their systems. Probably won't work but nice to take things apart & see how shit works.
So glad you appreciate this! Thanks for the comment, JonnyBoy!

I started playing this video but then I ran to the hardware store to by a bag of magnets. When I got home the video was still playing.
rrriiiiiiiggggghhhhhtttttt
Congratulations Martie !
You wasted money on gas and weak magnets.
Did you also pick up some overpriced, lousy fast food?
Love your work Phil. ..00..
Thanks, Billy Bob!
I use them on my scissor lift to hold tools instead of wearing my bags I use them to find studs I use them to drop in a box of screws and pull out a handful it's awesome
Great tip!
great detailed explanation of "how to" take door off
ikr. old video, old software, old school ways. So glad you liked this video on "how to take a door off a microwave".
I messed with the flux capacitor and went back to my high school days.
Did you buy Walmart stock?
Neodymium magnets easier to scoop from higher end charging docks with speakers and also can be saved from hard drives and optical drives.
Indeed! I don't throw out ANY magnets. Here's my hard drive magnet video:

I have a stack of ten magnets I got from microwaves. They might not be as strong as neodymium but they are still pretty impressive. My wife was confused as to why I wanted to keep the magnets so bad. Lol Magnets are just plain badass. Plus they are very useful to put on a metal tray when your working on thing's with small screw's and such. If you have ever accidentally knocked over your tray of important small part's you will realize how essential a good magnet really is.
Yes! I agree, Ben. Love those magnets!
My wife was like... "DON'T EVEN THINK ABOUT IT!" Especially that our microwave still works. They just can't see the beauties of science.
have her nuke a bulb in it. then she'll flip out.

These magnets look almost identical to the old TV cathode tube focussing magnets. These slipped over the neck of the tube and focused the electron beam on the face of the display tube.
Always useful for picking up metal items etc...
Interesting....
I have seen these type magnets in the bases of removable CB car antennas.
What about the brillo pad looking donut that separates the magnet n the housing it had gold spun in it right?
never heard that one
Well, i had a General Electric OTS (over the stove) microwave rated at 900 watts. Not only did its interlocks fail, but its controller failed as well, which resulted in the magnetron turning on when the door opened. Took the thing apart, and i actually took the MAGNETRON apart. Decided to use one as a coaster for my glass, and i still use it on my desk, in my room, even as i Ramble On.

excellent!
It was the twenty second day of April, in the year 2021, when i finally realized that microwaves use magnets! I'll crawl back under my rock now.
HA! yes!
I feel even worse. In my country (Netherlands) we use the word "magnetron", and I feel stupid to have never linked that to "magnets".
Also; the transformers from microwaves are used by some hardcore magnet fishers to DIY a very strong electro-magnet that is suspended from an hydraulic garage crane, to lift heavy objects like motorbikes from the waters.
I love watching the magnet fishing videos. When magnet fishing became popular, my video started getting A LOT of views. It's been good for business!
@@tubularap Haha...same! I just picked up a microwave by the side of the road simply for the magnets. Only after I realized they were in the 'magnetron' did I realize that's where the magnets were...and why it was named magnetron... : /
I have almost zero idea about this sort of thing, but when he cut the cable and took the top off, I immediately wondered, “do microwaves have capacitors?”.
So, yes. Yes they do.
Wow amazing! Just the kind of expert I need to rebuild my automatic transmission.
I think David was taking a jab at me. I found it humorous.
@@PhilCrockett Its all in love buddy.
I appreciate this kind of treatment, my friend! I live for it!
If you got microwave that has the spinning tray that motor gives out AC power you can power household light bulbs. I haven't tried any thing other than that but it's something to tweek on when your tweeking. Most lol motor you get out of eletronics are DC so here is a change
good call, Rudy!
Thank you very much for the video. Just got done watching how to get free energy for light bulbs from magnets. They what a lot of money for magnets. You have saved me money. Thanks
Glad you liked my video, Robert!
Thanks for the video of electrical energy with the use of magnet it will save me some money.
Sounds interesting..could you post a link to the light bulb video?
I had an old valve guitar amp that used to drop the valves out of their socket. I opened it, reached into the amp casing to get the valve and caught the capacitor. What a shock! Also the silver grid on the glass of a microwave is designed to stop microwaves as the hole sizes are much smaller than the wavelength of a microwave.
ZAP! I grew up on a farm. I know the feeling of getting shocked. Electric fences everywhere. We even had one that was 110 V to keep a bull in.
I laid my hand on a capacitor on a 5 ton A/C units. Almost peed myself I did but it clicked on after that
you only need to release the magnetron housing plate on one side. it will then be easy to remove, giving you access to one magnet. than bend both sides of the housing to reach the second magnet
thanks for leaving this tip, Ron
A word about the capacitor. Mfgrs built bleeder resistors inside the capacitors to bleed the high voltage to ground. Look at the numbers on the cap and usually you will see a resistor symbol that is attached to the leads internallly. The resistor has a very high resistance enough to bleed the high voltage down to 0 volts. It's always wise no matter what to go ahead and discharge the cap as a routine precaution. Like this guy says in this video.
Amen!
While in the AF I was an avionic instrumentation service and repair tech. This gave me access to capicitors which I'd charge in a wall socket and then leave lying in a common area of the barracks. It never took very long before someone would pick it up to check it out...Yea I thought that was funny.
I digress, if you're concerned about the capicitors found in electronic devices, I'd advise you wear a pair of decent leather gloves. I've worked on a lot of equipment mainly 480v and lower and it's true many of these capicitors hold a charge that's no joke. The ones I referred to earlier were smaller just enough to give someone a good shock without hurting them. Anyway the leather gloves and common sense will get you through anything you'll find in appliances or the old TV's.
THanks for the tip!
Question - for added caution should one carefully wrap a turn or two of electrical tape on the insulators to ensure they stay intact as i pull out other components? Looks like just enough clearance to allow fittings to pass by. The beryllium is really nasty stuff, don't want it to break apart as i disassemble. Thx
Not a bad idea..... Beryllium got a bad name for itself in the mining and factory scenes where a lot of dust and quantity of beryllium exists. Some people died from breathing all that dust over a period of time. Now beryllium is the "devil" because of those freak situations. Beryllium has been used in many products over the years like some cell phones, aviation, spark plugs etc.... if you go back far enough, it was even consumed due to it's sweet flavor. The fact that it can take high heat is it's best and most useful quality. I've been told that most modern microwaves don't use it any more, but I have not researched the primary literature on this in order to prove it. That being said.... it's never a bad idea to be over caution about all things. Someday we will be treating drinking straws like beryllium, and will be getting a lot of comments about how dangerous they are and how we're all going to die if we touch one. HA! Well.... Thanks again for the tip. Like I said.... never a bad idea to be over cautious.
Alright, hold up. I get that you're safe if you're careful, but it's not on the same level as drinking straws. Magnetrons' beryllia specifically is a confirmed human cancer agent by the IARC. If you turn that screwdriver too hard on a ceramic insulator, it'll be crushed, and you do not want to be directly handling crushed beryllia. There are safer ways to get these magnets; I'd rather just sell the magnetron and buy three magnets instead. They're going for down to 30 bucks on eBay, and they're buying for up to 10 bucks on Alibaba.
Don't they say the same thing about bacon?
The capacitors of any microwave from mid 1990s should have a discharge resistor built in so as soon as its finished cooking the cap discharges, ive scrapped thousands of MW never come across a charged cap, even old 1980s, what you need to beware of is the Beryllium ceramic as the dust from it if chipped nasty stuff, yes the purple / pink bit of the magnetron tube! . Most newer mw no longer use beryllium but you must be aware its deadly stuff like asbestos and only takes a small amount thats the scary part! Check my vids out of me blowing stuff up with thr transformer from one.
Great post! Hope other's read it. Thanks!
I do not recommend shorting the capacitors out because of noise sparks and high discharge that may ruin it! Use 60 watt 220 v bulb that will discharge the capacitor slower and without sparks. This I bet you didn't knew about it!
I didn't know about the bulb trick. However, I still say...."don't touch or mess with it at all".
@@PhilCrockett Bulb's filament acts like a bleeder resistor - to drain the charge from the cap.
i love this simple video because i now have an idea where to get round magnets like these to use for school projects i find also here in you tube. is there any other home appliance or device where we could get round magnets? thanks.
I don't know of any other ring magnets, but someone else might, that reads the comments.
old televisions CRT type
All speakers have round magnets.
Speakers.
Good work Phil, very interesting, but I wouldn't get you to fix my broken microwave . Ha Ha!!!!
HAHAHAHAHAHAHA!!!
