"Ok this is gonna be kind of dangerous but I'm going to do it anyway"
That's half of your videos
Later bringing an Oxy torch centimeters away from his fingers, meanwhile making small ball bearings red hot.
Will mess around with explosives, dangerous chemicals, fire, and an incredibly powerful magnet....
Yet gets injured by butter.
It was certainly good foreshadowing for the neodiddlium starting to travel at 3:18.
Danger is Cody's middle name!
@@discipleofshaun5252 You forgot that he drank cyanide.
When Cody says he was filming with a potato and you're not exactly sure if he actually did or not.
knowing cody a potato would be powering his camera just to prove that potatoes can be used as batteries
@@MrBluelightzero woosh
Woosh
If anyone could film with an actual potato, he'd be the one.
The joke
Bluelightzero's head
whooooosh
This is actually great! When you used that ferrite to memorize the field, it clicked how those old-school magnetic computer memories worked. Thanks!
I was curious how those worked!You blew my mind!(pun intended)
GIMME DA MEEEEEETAAAA

Hi
Wow. So obvious. I never really thought about it before.
"The overexposure is not the camera's fault" this man is a legend.
Revamped Outdoors true, it's the users fault.
Radom kitty is always welcome on CZcams, the original home of kitty videos.
The purring is so calming.
now i want some purring ASMR
Dogs drool... cats rule!

Learning about magnetism with Cody and getting attacked by a giant cat. It´s a great video.
meh, I can do without the cat, I'm here to learn
CAT
Next video will be about the attractive force cameras have on cats.
No put a magazine in front of you, that attracts cats faster.
Yes, cats like to sit on paper.
As someone with a STEM degree from an engineering school, I can't believe how much I learned from this video. For example, I had no idea ferrite magnets could be re-oriented like that. I also never realized horizontally aligned pieces of iron would repel each other in the presence of a magnetic field. Thanks so much Cody for making this old man smarter!
I am constantly amazed at the amount of (in my opinion) good knowledge I have gained from youtube. The most challenging part is finding the sources of the really good stuff.
he does do that... can we afford to let him go to mars?
I'm fairly certain that traditional (especially tertiary) education with the insane competition from independent and way quicker on their feet individuals and institutions online will sooner or later disappear. You're just living the future, as are we.
@Felix Merz - I agree CZcams is great for learning. However, it doesn’t completely solve the whole “you don’t know what you don’t know” problem. Most of the best education I received was learning answers to questions I’d never have thought to ask in the first place (and therefore never look up on CZcams).
truthsmiles That's an excellent way to put it
Thunderstorms, cats, and giant magnets! What's not to enjoy?
😂😂😂😐😐😳😳😳😉😉
The overexposure of the camera, the nuts and washers flying toward the magnet when you don’t want them to, the thunder, your cat, the burning of the table. The amount of things that went wrong in this video were hilarious and i love how you just went with it and uploaded. Its always an entertaining learning experience watching your videos Cody!
I agree, Cody has this homebrew way of doing things wich creates a relaxed and personal vibe, unlike some other channels wich seem to b more like a gameshow u just can find on tv.Never change Cody! u are doing fine...
I was hoping I'd find a comment like this! This shows true dedication to just telling people the facts, no funny business. Gotta love Cody for it!
Couldnt agree more, it feels like he just wants to show people something cool that he found, no gimmicks, just a guy who loves science and wants to share it with the world
Mistakes are often just another lesson learned.
Agreed. Cody's videos always feel so genuine, and representative of proper science experimentation. Stuff NEVER goes perfectly in the real world.
Great demonstration! my favorite part was when you had to let the cat in.
I can't help but notice that you've been slowly transforming into a wizard over time.
You're a wizard, Cody.
ah wot?
cody is a complete man... heats up magnets with a blow torch, centimeters away from his hand, sending red hot pieces of metal flying
He's a mad lad, my dude.
4:42 - 4:43 when he flips the magnet around is when the lighting flashes, you can see the black frame for a split second. Seconds later you hear the thunder.
Neodiddlyum, iron nuts. Yes Sir, how may I help you? 😃
I thought I was the only one that heard "Neodiddlyum" 0:38...
lasersbee Howdy ho, neighbourino!
Sounds like hes been watching too much AvE
Neodiddlyum yer nuts
Christ is watching
It’s the most educational cat video I’ve seen on CZcams
Haha, this is so true. There's literally no arguing with this point
Purrrrrr
Neodiddlyum? CodysLab is AvE confirmed
Looking for this comment
AvE is just Cody's uncle
I caught that too XD
@Drakoriyan Neighborino!
I want to know the story behind your right sleeve.
* plays with magnets *
* burns table *
- You know you are watching Cody'sLab XDXDXD
"i'm not sure if it's rather dangerous or not but I'll do it anyway"
Cody in a nutshell
true
Cody *would* make a great mad scientist.
"Neodiddlyum" AvE's rubbing off on you
This video's only been out a few minutes and someone else already thought this. I love it.
I was going to say something about that happening to everyone lately, but there was no way to say it without it turning into a "rubbing off" joke.
I heard that too and was like "did I hear that?"
Somewhere AvE is smiling!
Who is AvE?
Dipoles actually fall off as an inverse cube. So a magnetic field 3x as far away is 1/27 as strong.
this needs to be higher ppl. the opposite pole has a shielding effect.
Nope. It is worse. We have 2 dipoles. The interaction between ideal dipoles falls as an inverse 6th degree.
Took me till 3rd year university to have someone explain why magnets had way less range than the inverse square would dictate.
Let's learn about magnets here
Oh cool I can show my young cousin
I have an oxy acetylene torch here
*excuse me what*
2:45 is a good description for some of your vids!
If you had one of those magnetic field viewing sheets (if they have a specific name I don't know it) that could be fun to look at
This comment deserves more attention
+
Magnetic viewing film
Since we started the video with AvEish, might as well just call it magic pixie viewing paper, eh?
@@-Honeybee or.. Does this comment needs more ATTRACTION?
" I've got here my oxy-acetylene torch..." He said while sitting in the living room xD
It was very well explained with very few things. Nice!
Cat came to the rescue to meet that golden 10 minute quota
the vid was great but the cat angles really made it perfect
Cody would be the best dad! He sits with the camera like he is explaining to one of his best friends that always listens. Thats a real skill right there!@!@!@ Storytellers are the coolest type of people :P
Yeah and the friend is looking at thier phone. Hahaha
I learn more from this channel in 10 minutes than I learnt in a year at school.
This is fascinating! Loved it so much Cody! Great way to start the day!
Got to love the cats
WARNING I am the unprettiest human worldwide, but somehow I have TWO girlfriends. Join me on my highly stimulating channel, brother Ynkfin
We need a whole video of your cat playing with the camera. I'd watch that on replay for hours!

Why don’t you just buy a cat? You can watch it close up for years.
I have a cat, but the bastard hates people, doesn't let anyone pick him up and generally rarely does anything interesting :(
my cat always fought with me until the day i fought back and showed him im the alpha hahahaha. now he loves me and afraid to fight with me :p
@@rrkred3561 how do you fight back a cat without hurting it or generally make it hate you more lol
I enjoy that during a video, questions build up as its impossible to cover every aspect of a subject. But Cody seems to be good at coming back at the end and answering questions that he thinks the audience will be asking themselvs
The inverse square law with magnet is an approximation and only holds over a relatively short distance. It'll tend towards inverse cube as you move away because it's a dipole and the relative influence of the other pole increases with distance.
4:47
Thunder boomed right after the magnets collided. Cody is getting into some dangerous magical shit now!
Cody's power is growing.
Soon we shall all speak fluent AVE. It's just a matter of time.
I'm working on an AvE to Minionese translator.
Keep your banana in a vice.
MotoMatt what’s ave I’m sorry
FatCat919 a CZcams channel ran by a very funny man who has several made up words he uses quite often. He does a lot of different video types, mostly centered around tools/science/etc
Definitely check him out
Man I love Cody's simple setup for his videos, he's a humble man who doesn't need fancy stuff to amaze me with his astounding inteligence. Love from Brazil Cody
Magnetic force decreases with roughly inverse cube of the distance not squares . Because all magnets are dipoles. Near the magnet the field depends on it’s shape but overall at larger distance it’s inverse cube that dominates.
It depends if you are seeing it vectorially or with a versor, is just the same but in two different ways of seeing it. For instance Electric Field can be wrote as E0= Q/4pie0r^3 scalar multiplied with r vector, or you can wrote it like E0 Q/4pie0r^2 multiplied with r versor, cause r versor is r vectorial/ r norm, so yeah, basically is correct
I wish I understood what either of you were saying. :V
It's magic. The answer is always magic. Why else would the words "magnet" and "magic" start with the same 3 letters?
I thought the answer was, "aliens"?
no, it's magic
no its science
miracles :^)
fuckin magnets
Loved the guest appearance at the end. XD
The only channel with serious science, a hoodie with a massive hole in the sleeve, acetylene torches at the kitchen table, terrible lighting, lightning & thunder a giant cat and bigger than Ben Hur magnets. Doesn't get any better than that.
This is possibly the most interesting video you’ve made in my opinion. As a kid I was always interested in magnets and played with them all the time for hours.
Your fingers were scary close to that torch. haha
Yeah I was surprised the thermal conduction didn't burn him
They were balls so there is not much surface area between each one.
lack of depth perception due to the video, he moves the torch forwards after he heats up the balls. furthermore, he only touches the flame to the balls for two seconds at maximum and like Samuel said, low surface area. no harm here
Tommy Callaway ,
I wonder if that’s where that big burn hole on the arm of his jacket came from.....
just cause of the lens
4:50 - Ooooh, thunder... You lost me right there, I want to go watch out the window.
My mother tells me I was an odd child. When we had an electrical storm, we'd unplug the TV - for safety - and I'd be perfectly happy with my face glued to the window watching the storm.
My younger brother would cry at the noise. I'd only get upset when it stopped!
Unfortunately in the UK our storms usually suck. Mainly sheet lightning. A few years ago I was in Budapest when a huge storm rolled in... Full on forked lightning, and that was me happy for the next hour, on the balcony, beer in hand, getting absolutely soaked (it had been over 30C all day, so I was happy to get rained on). Got some great photos too.
I like magnets too :-D
rain is like a mental shower for me
I thought liking storms was the default... Sideways lightnings, really dark days and evenings, seeing how the density of the pouring rain changes in the distance. All the cool stuff, weather is cool, even fog - walking *inside of a cloud*. Never understood why people are so upset about these rare events, apart from the obvious "it's dangerous", but noone ever tells me how they don't like fog for being dangerous to drive through.
I agree, standing in the rain watching a storm is always a great time. When you actually need to be somewhere, and preferably dry, it can be a pain though. And *driving* in pouring rain sucks hard. As long as you're somewhere at a time when you can just watch and enjoy it though it's great fun.
I felt the same way. There's something simultaneously terrifying, majestic, and serene about thunder and lightning
Haha you my dude made my morning.
For some odd reason 😂
Awesome, very informative in an understandable format. Cody excels as usual
Thank you for leaving the cat in at the end😄 it was a good laugh and solicited a few “what a good boy’s” form me 👍 keep it up Cody you’re awesome
0:37 did you say "NEODIDLIUM" magnet? AvE is everywhere!
Flander's Lab
Indeed he did
I noticed that as well. Ive been hearing AvEisms on soo many unrelated channels lately
keeping his dick in a vice
I was waiting for someone to comment this!
4:49 no wonder the cat wanted to be in
also i get this mad scientist vibe^^
@Ungregistered User I was thinking to cat was scared by the thunder, thus wanted to be in a safer place
I learned something new when you used the puck magnet to flip the polarity on the ferrite magnet. Didn’t know that was a thing. AND I want one of those igniters for my torch. Wonderful video that I’m sure made my neighbors think I’m crazy when I started jumping around screaming that I learned something new.
This man deserves every single like, view and subscriber because he is one of the few people on CZcams who still does his thing with heart and passion. Thank you Cody for everything!
Well done, and well explained :)
Also, upvote for the cat!
I've learned more from your videos than every class I've ever taken.
Keep doing you man looking forward to yet another interesting topic.
Wes Sleeps I’m in chem class watching this video after taking a test about frost wedging chemical change physical change and other stuff I learned 3 years ago from watching Cody’s videos
I wish the Mars project was still a thing
American schools... what cody showed in this vid we germans learn in 8th grade
I hate when people say things like this. If you're in a school where you're learning more in a video, than an entire class, something is wrong. You should be learning an order of magnitude more material, at an order of magnitude more in-depth. (So either you're sleeping in class, not applying yourself and doing just the bare minimum, blaming someone else for your lack of education, or are using hyperbole. Which is it?)
@@xenonram Rodger that you have missed the point confirm readback.
I love me some cody's lab. Thanks for posting videos all these years
Hey Cody, great video, iv'e quietly wondered the reason but never enough to warrent a google search so im glad you made a video on it. plus i'm happy you kept the cat in there. made me smile.
keep up the good work.
David
Your videos are spiritual for me. Often saving my life. I love you bro and look forward to your teachings of knowledge.
We need to create an AvE dictionary/encyclopedia.
Already been made, Google it. Has hundreds of entries.
There already is one actually. I saw it linked somewhere some time
Here's the link:codepen.io/LegoLife/full/YVXbMR
thanks for the link, i'm not as satisfied as i thought i would be though. the creator of that collection got half of the stuff wrong
What's AvE?
I mean this in the sincerest way possible, it's hilarious how much common speech you share with AvE. I'm a fan of you both, keep up the great work.
Most interesting video I've seen lately! Thanks for explaining this and creating this video!
I had no idea there were magnets like ferrite magnets that could change orientation like that.
I recently made finely powdered cobalt and it is equally as awesome as Fe3O4. I've been thinking of making a ferrofluid with the cobalt, but I think I'll need to form even smaller cobalt particles.
Great explaination as always Cody. Loved your feline assistant.
Good, cat was making sure science was sound!
The cat at the end was wonderful!
Hi Cody! Real interesting! Thanks. Love the kitty at the end!!
Ahh that thunder is sooo satisfying! Who'da guessed a thunderstorm makes such great background :) Love it!
I was thinking the same thing haha. Do you find thunder quite relaxing at night? I know I'm in the minority of people that do haha, but if you do, then I respect that!
Hey Cody, the weather makes the perfect mood for jacobs ladder experiments during a thunderstorm! "gonna be kind of dangerous but I'm going to do it anyway" :)
This is such a great way of learning, you are a good teacher
Thank you for the awesome explanation Cody ! Keep up the good work man. 👍
Your cat tax has been paid in full.
Next payment is due in one year. Be ready Cody, get those cat ideas flowing!
"This is rather dangerous but lets do it anyways" 😂
Amazing video Cody. Thank you once again.
2:49 ...You are a Hairy, Wizard! This is spectacular! I love hearing you explain about Science... the real magic.
And talkative cats apppear to be attracted to magnets ;-)
Hi Cody, great video! Your description was really good actually for the mechanism at the end, but it does miss out a bit on a detail. You were talking about 1/r^2 effects, but actually I think it is higher order than that. Your explanation is correct I think for a permanent magnet where the nut is, but because it is induced the effect is even stronger. - you end up with Hamiltonian terms going at 1/r^6 with two such magnets, but with only one I think it drops a couple orders. Magnets are crazy complicated though - your qualitative explanation requires a lot of work to formalize, and this is the first time I've seen someone come even vaguely close to right - kudos! :)
Doesn't it depend if you're reffering to force or energy? One is the other's derivative
@@sidewaysfcs0718 It does, but even so it's not going to get down to r^2. These induced dipole forces are pretty crazy - you can get terms that go like r^-12! Those are actually the ones responsible for not letting atoms walk through each other.
That's actually really interesting. I never considered how non-permanent magnets like this works, but now I ALSO understand how magnetism in ferromagnetic materials work, what separates permanent magnets from a non permanent magnet, and how the Curie point affects this.
Finally see the connection between all the random bits of information I got from Wikipedia over the years...
Your videos are so interesting. I find myself watching 1 or 2 every night. We need more people like you, that can make science fun and interesting.
That is totally nuts Cody.;)
Wehayyyy, I like it! That was up there as a top pun sir!
*KITTY ATTACK!*
Cody spent 10 minutes explaining magnets, but all that anyone can think of is a cat =D
Truly, the greatest power in the Internet is cats. =^o_o^=
haha I love this comment - how do they have such power over us!?
Meow
@@TommoCarroll Because they're the coolest pets on the planet. End of story!

I need more of Cody's real laugh in my life. I really enjoy how purely he cares for animals.
5:04 opposite poles repel. Heard it here first. Love the videos Cody.
That's a nice neodiddlyum magnet you got there
Just dont try to touch it while doing experiments with other magnets
Quit flirting with Cody
Imma call them Neodeadlyum from now on
Hes been watching too much AvE
You need to make a video that's all about the cat. Right meow!
What a lovely big tiger
Yeah, every channel has to have its own cat. :-)
< I have a Cat or its a really fluffy pillow
LoL whats the into going to sound like welcom to CodysLab and the scientific mistry of cats
That was really cool, goes way beyond what I learned in school. Thanks, Cody!
Most excellent video. I learned so much here, thank you.
Put the cat's face in the thumbnail for quadruple the views. xD
A name it some buzzfeed worth title "What happens when you stick a cat near a magnet!?" and you're onto a winner!
Experiment ended in cat-astrophe!😁
Cat-ass-trophy?
Hahaha nice 1
Hahaha
If you ever won a competition and received a cat ass trophy, to say that your emotions would be mixed would be an understatement! haha
I remember, in a french science museum, the _Palais de la Découverte_ , they had a demo where you could actually listen to the magnetic domains flipping in a bar of iron :
There was an iron bar with a copper coil around it. On top of it was a permanent magnet. the ends of the copper coil were fed into an amplifier that itself fed its output into a speaker.
When the permanent magnet was gently turned, magnetic domains in the iron bar would flip. They would do so quite brutally, leading to small but sudden changes in the bar's magnetic field. Those would induce small spikes of current into the copper coil, that would get picked up by the amplifier, and sent to the speaker. This resulted in a crackling sound, as the magnet was turned.
Great content. I've learned alot on this channel. Keep it up!
The cat should definitely crash more videos...lol
If you want your shots not to be over-exposed, point your light source away from your person and bounce it off of a white surface. You'll get much better diffuse lighting versus direct lighting.
Simple, great advice right here!
Pretty sure the lightsource here was a window which is a bit hard to point heh
You can point the light from a window using just white cardboard or something.
The diffuser was helping near the end of the video.
Perfect alchimistic explanations: thunder in the background, cats stolling by and Cody playing with magnets and fire so he can burn his table...
Next time on this channel: the portion on health, brewed by Cody using natural electric force of a thunderstorm (insert insane giggle here!)
Glad to see how well Cody handled the whole thing with youtube not allowing him to do these huge projects. Still just as good in my opinion.
"On an almost atomic scale" - you're actually precisely correct. The poles of each atom are aligned.
Surely that makes him wrong since he said almost?
@@squidasylum181 in this context, the usage of the word 'almost' can sometimes mean 'presumably'. Linguistics are exciting and challenging because they are rarely ever black and white.
@@KurtRichterCISSP I really don't see how you can interpret it as meaning presumably, since it has a clear literal meaning that makes sense in the context. I have never heard anyone mean almost to mean presumably.
I'm curious now, how many nuts and bolts can you join together that way before its not strong enough?
Depends on the strength of the magnet
Best Cody’s lab video ever for the surprise at the end :D
I forgot how good a teacher you are. Very fascinating!
5:04 Guess you meant SAME poles repel ;)
Sigh... yes, I messed up.
Someone will take that part of the video out of context (or without a grain of salt) and will use it to try to "Prove" that the earth is flat.. Good job Cody
/s
Poles don't repel, we're just regrouping
@@theCodyReeder You're just a human, I won't put the blame on you as no one should.
Just to check if you're listening.
Wow, magnets AND a cat? Please, explain how cats work now. Oh.. right, they do not.
Introduce a mouse into the situation. Cats can be a bundle of energy, and keep your grains safe.
Don't you get it skarholmen? Cat's work *_via_* magnets! It's just simple physics!
Fucking cats, how do they work.
Stephan Brun underrated reference
Excellent explaination !
Perfect video Cody thank you.
I like being educated. thanks!
“Neodiddlyum” AvE crossover episode when??
Extremely interesting. Thanks for the video.
cody's finger magnet must have been going crazy through that! Also bonus points for the adorable kitty
