I don't know why I feel like i just got one of the best abstract lessons in math and physics here. I'm definitely looking at this later tonight. I figured out the mechanism but I'm just fascinated by how awesome this is. Very cool.
I like to think of it as dropping the ball down a hole and hitting a target at the bottom. It takes as much energy to remove the ball from it's resting place as it had when it hit the brick.
This rail gun seems to violate conservation of energy and momentum. However, why it doesn't is interesting. The electromagnetic force is fundamental; and a magnetic or steel ball would be attracted to it by the very nature of the force. This releases the potential energy of the field, and removing the ball requires kinetic energy which keeps us from violating any laws. Energy is actually an emergent property and doesn't actually exist, but it's very handy for doing the math and explaining many things.
Same! I'll be using that idea for some much much smaller magnets I have. I've shattered a few of them because I wasn't careful enough when putting them back together.
No sarcasm: I am genuinely impressed he has all his fingers, doing this kind of thing. I've worked with much smaller neodymiums and they still scared the bejeezus out of me.
I have some very small ones. When he pulled the first set of magnets out of the box, I thought, "How are you going to get those apart?" Shows my lack of imagination.
OMG!!! These magnets must have cost a fortune! I've never seen a more impressive table-top demo of the power of super-magnets! Very interesting...WELL DONE, indeed, Mate! Brilliant!
Was thinking the exact same thing. This guy knows what he's doing. This is massively dangerous. I've handled magnets a fraction of that size and they end up crushing each other. Not to mention attracting steel objects. You really need to know what you're doing. I wouldn't even order these. No way.
We used neodymium magnets at work to hold large plotted maps to the wall. The wall had been painted with 5 coats of magnetic paint. It was paint filled with iron filings. A 5 gallon bucket weighed in at 120 pounds. We called it the iron curtain. The magnets worked extremely well. But even some of our larger ones would shatter at times. And yes they were somewhat expensive, but they prevented having nail holes in the wall and allowed the maps to be changed out daily.
I would be scared to even be around some of them larger magnets. Magnetic forces are no joke! Literally bone crushing if you don't know what you're doing! What I find really cool is that the fields in the last pair are strong enough to actually capture the projectile!
This is just speculation on my part, but I suspect it would be impossible to make a setup like this where the projectile isn't captured by one of the pairs of magnets. Since the only reason it isn't caught by the very first pair is the presence of an even more powerful magnet further ahead. So no matter how fast it gets, it can only move as fast as the strength of the next magnet.
I was thinking the sphere would have more force before the last magnet, meaning, if the brick was placed on top of the last magnets the ball would have been drawn through it rather than trying to stop just before it.
It is awesome that the video it is just the content that I was hoping for. No jokes, no opinions, no long explanations, just what the title says and no more. Thanks!!!
if you think abt it you could just make a bigger/stonger one with those electric magnets and turn the magnetism off at the right time and it should go forward
If the pull was continuous and negated at the end. What propulsion, with a gate that pauses motion instantly. With a lot of these in a central emanating, point 360° is possible for movement in any direction.
@@hiya2112 side up my pinky finger got smashed between 2 very strong magnets. Smashed flat too. Took a long time to heal and never quite grew back right. Ha
Yeah, people forget that magnets are ceramics and that the plating is there to protect them (especially from oxidation) and to keep everything together. If you've ever dropped a refrigerator disc magnet and suddenly find yourself with two of them, you get it.
@@hiya2112.....I bought some cheap neodymium magnets from Amazon about the size of a quarter ($0.25) and they have pinched the cat-walking-dog-shit out of my fingers drawing blood blisters. These magnets here are hundreds of times more powerful than the ones I got so these are indeed dangerous. They truly would make you shit your pants if you got a finger in the way.
These magnets were not around in 1980s when I entered a Physics competition to hit ping-pong balls through hoops but I suggested electro-magnets. I was maybe 14 and didn't make it to compete. Glad to know my idea with actualy magnets probably would now :) Really cool vid. Thank you.
I swear, magnets are the closest things we have to magic irl. They're physical objects that can influence other objects without touching them. I do not understand how they work at all lol I remember trying to look it up but I think I both forgot, couldn't pay attention nor understand. I need to look it up again
There's a reason why magic in books/movies is usually accompanied with sound. For example, in Harry Potter they have to speak the spell/curse. This is because "magic" actually is sound vibrations and magnetism and how it can alter so much around us. Look at gravity, look at the Earths electromagnetic connection to the sun, it IS magic!
Fucking magnets, how do they work? But seriously, the reason magnets seems so magical is that they don't typically occur naturally. The atoms in a piece of metal are normally arranged in a random orientation, and so aren't magnetic.
The dipole (polarity) of the molecules are all aligned in a magnet. So put simply the molecules are nice and arranged. If you heat up the material the molecule start to vibrate and rotate directions and you will no longer have a magnet.
@brmnplayr science is amazing fellow human, you should learn more you would be amazed what you find. For instance magnetism is only halve of one fundamental force which is electromagnetic, being that they give rise to each other, which is possible to graph using wave theory and 3D. And check this out if strength is your fancy there is a fundamental force that is 100x stronger than electromagnetism, have fun researching.
Something about the way the bearing stops at the end of the track reminds me of the roadrunner cartoons. All it needs is the beep beep sound dubbed in.😂
Neodymium/rare earth magnets are extremely strong, but very brittle. The use of the wood wedges was a stroke of genius. They're not like normal (ferrite) magnets - if rare earth magnets smash together without the wedge, they'll be in pieces. I don't think a lot of people know how potentially dangerous they are.
I love the line in Pink Floyd's song "High Hopes" "in a world of magnets and miracles, our thoughts strayed constantly and without boundery.......' Always fascinated by magnets, just think of the things we could do if they didn't want to flip so bad!
2:40 that's some insane trust on the magnet! I get that it's consistent in its behavior but that still startled me lol. Like that professor who showed off a pendulum with a bowling ball and stood in place without flinching
This is impressive! I’m curious along with increasing the size, what increasing the space between them does? I suppose if you made the gap too large, the pull-back of the magnets the ball is “leaving” would be too great? Idk, just curious what you have learned about this spacing.
You got way too many of the great magnet's to play with. Nice to see that you have learned the proper way to handle them and I hope everyone has learned from it.
Reminds me of a friend of my brothers back in high-school that had 2 hockey puck sized neodymium iron boron magnets. He would walk through the halls and occasionally toss them at lockers. The sound it made when they hit the lockers was like an explosion going off. I'm still surprised he never got in trouble for that. Those things could easily smash bone if you got your hands trapped between them
Yes, neodymiums are pretty scary. They're a bit expensive, so play with them wisely- they tend to be pretty brittle. You let strong ones smack into each other, and they can shatter.
Technically, it is in fact the weakest, or second weakest if you count gravity. But when you play with the stronger ones, you tend to destroy cities instead of bricks. 😇
Great video. Why did you need to use the wood trick to join the middlemost magnets together...? I realise you needed to use the wood to position the more powerful magnets on the plate and stop them slamming down.
To make a long story short… I picked up the lid (the magnetic part) of a 3 inch ErieZ model B trap separator. A nearby pair of those big Channel Lock pliers flew a couple feet and mashed my thumb. Lost the nail, but no write up’s or OSHA reports. All in a days work.
Very cool. My son worked with a magnet at university that would destroy your wristwatch. You had to be trained and certified to be in the room with it. Scary stuff.
That was probably a supercooled electro-magnet, eg as used for neutron magnetic resonance (NMR) experiments. Not only can those magnets destroy eg a wrist-watch by simply pulling it in at such a speed that the watch gets mechanically destroyed at the impact. The magnetic material, eg the wristwatch, can disturb the magnetic field in a way that it leads to the (liquid helium?) coolant boiling off, possibly in an explosive manner. I was allowed into an NMR room once, and was more or less strip-searched for anything magnetic like watch, keys, wallet with coins etc and having to leave it all on a tray at the entrance. Apart from the obvious danger to life and limb, an NMR device boiling off catastrophically can be damaged, and if not damaged is complicated and expensive to restart.
2:50 - Pull the left end of the track up, to create a angle 📐 at the other end where the ball is to assist with ball removal. I like your wedge and slicer for adding and removing magnetss
Very entertaining video. Now set up a mirror configuration on the other side of the big magnet. Test how much force is exerted when two metal balls collide in the center with nowhere else to go.
The wood is not just to protect fingers. Neodymium is very brittle so without the wood, some of these magnets would instantly split and chip on contact. I use electrical tape on the edges of mine to limit chips and cracks.
Hmmm yes yes but what happens if you put something in the balls path to the big magnets at the end? Does it plow right through or does it prevent it from reaching its goal?
I'm sure that depends on the something. The magnets pull with a certain amount of force, so if the something is strong enough (like a heavy object with a lot of friction), then the ball will stop, otherwise it'll push it out of the way or break it.
Be carefull, eveytime the moon passes over your house ( or your house moves under the moon ) it will be pulled down a little if you keep playing like this ;-)
Vor vielen Jahren las ich mal eine Abhandlung, dass, basierend auf dieser Technik, es möglich sein könnte, über große Rampen Flugzeuge oder sogar Raumschiffe in die Luft zu katapultieren, um so den großen Treibstoffverbrauch zu reduzieren, der beim Start immer anfällt.

I'm curious why you never use a Halback array. It seems to me you should be able to place the magnets in a halback array pattern, but gradually increasing in size over the length, as with your other accelerators, to achieve a much stronger effect. No?
A "Halbach" array will not be useful at all in this use case because what it does is deforming the magnetic field so that practically all the magnetic flux is on one side. To achieve that you use 4 magnets and you get a field that is less than twice the strength (the other half is wasted canceling the magnetic field in the other side) so equivalent to two magnets put together side by side. A halbach array is useful if you want to confine the mangetic flux to one side only or if due to cost of space constraints is better to use 4 smaller magnets instead of a bigger one of almost twice the strength.
I use tiny neodymium magnets in scale modeling. Even something as tiny as a 3mm x 2mm sized magnet is surprisingly strong. Not finger crushing, of course, but it takes more force than you'd think to pull them apart for an object that small.
Do you know where I can get something significantly stronger than the ones at Hobby Town? the ones I got there just aren't cutting it for the model I'm trying to magnetize.
There was a video put out a couple of months ago titles "What Animation vs Physics Got Wrong." involving stickman and the representation of physics. Your video disproves one of his main arguments about increasing speed through a magnetic field. Awesome. Well done.
It doesn't disprove that. The speed that the ball has at the end here is, at best, the same that you would get just using the last (strongest) magnet. At least thats what I'd assume and since there is no comparison shown, there is no disproving anything.
If one metal ball is already sitting at the big magnets at the end and you shoot another one into it if it's enough to knock the other away from the big magnets it should shoot with the same force that broke the brick shouldn't it?
@@The_Music_Source or if the Ball that is being shot out of the end is made of something OTHER than steel, like Brass, and you use the steel ball to push and propel the non-steel ball, that has potential for quite a bit of force if you can get it fast enough! i think trying to make this a crossbow with like an arrow/bolt would be super-tricky unless you're using like a square-magnet running along a u-shaped channel bushing an arrow, would be easier to use it like a railgun slingshot either knocking into another ball like you said, or pushing a non-steel projectile

A halbach array is useful if you want to confine the mangetic flux to one side only or if due to cost of space constraints is better to use 4 smaller magnets instead of a bigger one of almost twice the strength.
Спасибо за интересное видео. А про создателя кирпичей ещё не сняли видео?
Damn, he needed a special mechanism just to separate the friggin magnets! That's a sick setup he's got tho.
Great idea, powerful AF! 💪🏼
Magnetic cannon :) that was awesome , thanks .
Next video: we won a DOD contract to create electromagnetic railguns for the us government.
This is one of the most fascinating things I have ever seen.
I have seen many things.
I use tiny neodymium magnets in scale modeling. Even something as tiny as a 3mm x 2mm sized magnet is surprisingly strong. Not finger crushing, of course, but it takes more force than you'd think to pull them apart for an object that small.
Do you know where I can get something significantly stronger than the ones at Hobby Town? the ones I got there just aren't cutting it for the model I'm trying to magnetize.
@@legionaireb Magnet Baron is where I get mine. Specifically the stronger N52 magnets.
There was a video put out a couple of months ago titles "What Animation vs Physics Got Wrong." involving stickman and the representation of physics. Your video disproves one of his main arguments about increasing speed through a magnetic field. Awesome. Well done.
It doesn't disprove that. The speed that the ball has at the end here is, at best, the same that you would get just using the last (strongest) magnet. At least thats what I'd assume and since there is no comparison shown, there is no disproving anything.
2:38 your bald? Also face reveal😂
agree🤙
Genuinely impressed. Youve almost got yourself a rail gun. Good job. 😊 new friend, full watch.
Please note that it's just a fire brick, not a house brick
$10K in magnets and you have a neat toy !
I got to admit, this makes me curious if you could make a crossbow out of this system somehow
I think the hard part would be getting the animals to wear all these magnets...

Railgun
If one metal ball is already sitting at the big magnets at the end and you shoot another one into it if it's enough to knock the other away from the big magnets it should shoot with the same force that broke the brick shouldn't it?
@@The_Music_Source or if the Ball that is being shot out of the end is made of something OTHER than steel, like Brass, and you use the steel ball to push and propel the non-steel ball, that has potential for quite a bit of force if you can get it fast enough!
i think trying to make this a crossbow with like an arrow/bolt would be super-tricky unless you're using like a square-magnet running along a u-shaped channel bushing an arrow, would be easier to use it like a railgun slingshot either knocking into another ball like you said, or pushing a non-steel projectile

При изготовлении данного ускорителя ни один палец не пострадал😅
Yes, I expected bruises, bloody blisters, and black fingernails!
