- Bone Crushing Magnets!
Oh! My! Goodness! Neodymium magnets are some crazy-dangerous things! In this video, we see just how scary N50 magnets can be!
SPECIAL THANKS to @supermagnetman for all the coaching and help!

I worked on lsm systems for coasters, I would be really impressed if you pulled this off. You're timing has to be exactly right or you end up slowing down the car. I would suggest doing an lim.
It’ll be a challenge for sure, RanHam335!
Gonna try using Arduino with optical sensors to fire the coils ( 3 of em, I think). That way, timing can vary based on load, etc. Gotta be a hundred things I’m not thinking of yet. Any advice you have to offer is entirely welcome!
@@WillPemble My advice would be that you need to build an Energy Storage. The Tesla Model 3 has an 355V Battery that can provide up to 1100A. So i would recomend that you build an big capacitor bank made out of Supercaps that can provide this huge ammount of Energy in seconds.
I use a bunch of small neodymium magnet as fridge magnets. I got them from disassembling hard drive.
He should have more subs
Oh wow, it is going to be a magnetic launched system!
Yep!
amazing
You should be using a small format PLC system instead of an arduino!
Hey Will do you have an idea of when the coaster will be completed
I think you are really cool! 😎
Well chicken bones are hollow, so it would require less force to crush
be careful with this. You seem to really be doing all the math but you dont wanna be that guy who killed someone with a homemade rollercoaster
How do you get all the money to do this stuff?
So excited for this project. If anyone can do it, WILL can !!!
The force is strong with you, Will.
Blunder Magnets are dangerous.
Soooo dangerous! Especially because they look entirely harmless! 😯
Yeah okay, magnets are terrifying.
They really are!
Scarier than fire, if you ask me!
@@WillPemble No doubt!
those are massive. jealous
They’re scary big!
Gotta be super careful with them every minute!
@@WillPembleI bet. I used 1in discs for a project once and they were really difficult to separate by hand. I'm curious to see how many pounds of force just those two have. I imagine with a few you'll have one whiplash of a launch!
That's cool but how did you get them apart??
That was a cool video. Magnets are fun. Wow, those are dangerous. I am looking forward to seeing the new Coaster.
I have seen others use a wooden lever system to slide the magnets apart very easily... sort of like a paper cutter, only different! lol
This is awesome man
how do you get the magnets apart?
I can’t wait for the next Update on this coaster.🤩
Do you allso make magnetik breakes?🤨
You bet!
Gonna use eddy current braking to slow the thing down!
Will Pemble ahhh thats make sens
4:20 imagine how disappointed I am that it's empty! And how impressed I would have been had it been full!
Should have used a full, sealed coke... now that would be interesting to see...
Bird bones are weaker than mammal bones (most of the time). Plus when an animal is dead the bones are weaker. And then once you cook the bones they become even weaker. So... I am not sure about the comparison if the chicken bones to the human bones.
Cool video though! I look forward to the next part.
Excellent points, Willby.
But I’m still not gonna get my fingers in between those magnets :p
I was literally going to make this point as well. So glad I’m not the only one. But I also agree Will I definitely would not want to risk further testing just to find a better comparison
Thanks, Blackhawk!
Those magnets scare the heck outta me! Don’t get me wrong... I love them, but they scare me! Hahaha
I'm surprised that you've decided to go down the path of an LSM launching system. LSMs are reliable, but they're hard to align properly so the cart accelerates rather than decelerates. Personally, I'd look into an LIM system if you're sticking with the electromagnet idea. If you have the budget, a hydraulic or compressed-air launch would probably work best since they're easier to set up, can accelerate quicker, and provide a constant acceleration speed if done properly. (Continued below)
If you were to hook able to use an air compressor and release all of the pressure at once, you could, in theory, use that pressurized air to turn a drum and pull a cable down the launch straight. There is a great video by "Art of Engineering" on CZcams that explains how the cable, drum, and catch car all work. Although the video covers a hydraulic system, you can probably engineer a solution to work on 4,000+ psi. Again, the magnets are a good idea, I just worry that you won't be able to reach the speed you need to get to in time. (I'll show numbers below)
(Part 3) To reach 21mph in 0.8 seconds, you'd need to accelerate the car, with weight, at 11.76m/sec. (roughly 1.2g of forward force). It would take a pretty strong magnet to achieve that type of acceleration. Can it be done? Absolutely.
And please don't take my comments as criticism, I applaud your ingenuity and knowledge about this stuff. I just want to present other options in case something were to happen that doesn't work in your favor. I wish you the best of luck and I'll be keeping up with your progress every time you upload!

The chicken bones would have been ok, that is if they weren't cooked
I’m not sure a chicken would agree 😂, but I totally get your point, Eric. The cooked bones are brittle.
This guy is like bill nye
Can i hire you and pay you money for building a roller coaster
yes or no
Esta muy bien todo voy a tratar de acerlo muchas gracias dios lo bendiga
Ah yes, I see how you are working on your “how to bend pvc track” video good, good.
(I’m joking)
3:50 video starts here
No it starts a 0:00
I'm not going to ring the bell, but I'm already subbed, and I clicked "like" before you said "hello".
Thank you, Doktor Jim!
I’m so grateful for your support :)
Docktor Jim haha same
One of the next Videos will be Sponsored by Nord VPN 😂😂😂 I bet that!
I bet you can get away quite well with old Transformers from old Amplifiers or similar. Make sure to get the magnets so close to the electromagnets that they barely not touch
Hurry up and build this thing already lol
Going as fast as time and budget will allow, MKONE. I promise!
I can’t wait 😃
I wouldn't even expect this good filming with someone at 100,000 subs
Hey man, love your content, but that bone was cooked... Try it on like a raw chicken leg...! 🤗
I really should, Alex.
But we gotta keep on keeping on!
Much to do. Gotta build the cart, design the launch system, the breaks, the rest of the track, etc etc.
@@WillPemble There really is sooo much to do... I can't wait to see the outcome though. Wish I had the tools and skills to try something myself. Maybe one day 🙌
Where do
You get get these?!?!
My pal George George Mizzell at www.supermagnetman.com has all the magnets you need! And check out his videos at czcams.com/users/supermagnetman. Everything I know about magnets, including how to safely do this experiment, I learned from him!
:)
0-21mph in 0.8 seconds??
That would be only 1.2g. The highest g i can handle :(
i feel like something you could do is have a magnet sit below the car and have an other magnet behind it that can repel the other magnet along the track. You could use something like a pole to push the repelling magnet down the track.
What's the point of using a magnet then?
@@azertycraftgaming ok never mind, scrap that idea.
@@probxtion1995 xD
You should come to my house
Mr Jaxson Jay and my house.😁👍
and we already got idiots in the comments who think they're first
