Excellent video,explains the mechanism very well. Couple of questions: Could this be done with electromagnets instead of permanent magnets, and how much mass can this model carry?
I was hoping to magnetically levitate my wedding band. I guess It was a little naive to think that I could do this with a hard drive magnet, dry ice and a tungsten carbide ring. The threshold for tungsten is almost -300˚ f and dry ice will get you to like -50˚ <--- sheer disappointment
Would anything in the external environment alter the magnetic field? And yah, the warming problem...I guess that could be used to stop the car from moving...
also, would drilling holes in the superconductor make it not work, or work with less efficiency? (holes for the purpose of circulating cooling agent in a loop.)
As far as I know, it also works upside down - magnets over the superconducting disks. according to the 1:18 diagram, there would be no/far less of a magnetic field cushion. Can you explain how it works?
What makes the car start moving suddenly? Also what would happen if you had a whole surface of magnets, rather than a track? Would the magnet be able to go in left and right, as well as back and forward?
Really cool track! But it's flat, i.e. in 2 dimensions.... See a video of such a levitating train in 3 dimensions here: moebius dot youtube dot mosem dot eu ;-)
@jaquari1997 No glue is needed. Just rough up the sheet metal with some sand paper and that will increase the friction between the magnets and the base.
So in the future roads are going to become EXTREMELY expensive...filled solid with Magnets...^_^..So the person who comes up with the super effective manufacture of Magnets is going to be the Next Henry Ford...^_^
@andrea13971894 Basically cos the magnets are both attracting and rejecting it at the same time so it moves because it's attracted to the next magnet and being rejected by the one it's already over... I think
WOW Lab, i'm currently trying to make a track out of electromagnets. I'm aware that you mentioned that we need 1/2 a tesla magnetic field to levitate the object. Then the 'train' will be made out of horseshoe magnets. AC current is used for propulsion. Can you comment and give some suggestions?
@WOWLab can i replace the superconductor into anything else? i mean, not cooling it, and how long can the superconductor remain its temperature in room temperature? will it become warm soon?
What force pushes the vehicles forward? Thought you should have some kind of alternating field or something, but your car just moves forward after it is cooled.
@Quarker99 only with an external force like pushing it or the gravity if the track is inclined, but because the friction is so low, when u push it it moves for many seconds
The major issue is that Space is a vaccum, there is no Magnetic fields in space so it would not work. The only possible way of space transportation is sadly Jet engines.
@swish1234567890 At 2:20, you can see them pushing it forward, which starts the motion. Then, because of inertia, it stays in motion until something stops it. Because the track loops, it will keep moving forward.
wow¡¡ ,ok exelent¡¡, but what kind of stuff can make the superconductors to reach that temperature.?., and what would be the cost ?, but any way this can works a thousands better than the actual transport
There seems to be confusion about how this works. In a hope to clarify thing, there's no magnets alone that will reproduce this experiment. Sorry to disappoint, but we can't have floating cars by stuffing enough magnets. In order to have levitation, a conductor must be turned into a super conductor by cooling it enough (as mentioned in this video, -166C). The conductor will then always be repelled by the magnetic fields, thus make it floating.
It really needs at least 3 magnets? Can't it be done with just one? I mean, if the magnet levitates when placed above a superconductor, isn't the other way around possible?
@xineisBR Sure thing - it just gets very unstable if you only have one magnet. Having three or four in each row allows the train to handle the curves better.
The thing is, I'm actually working on a superconductors project for my school's science fair here in Brazil!
So, I REALLY need every help I can get. Do you think that using coils would make it stable?
What I mean is building a metal track, like aluminum or else, and under it, we'd put some coils, so we can control the intensity of the magnetic field.
Also, do you happen to have any material concerning the theory of it?
@xineisBR You're going to have a hard time making a coiled electromagnet strong enough for this application. Look up the Biot-Savart law for a solenoid and you'll see that you need many many coils and lots of current to make a strong electromagnet. To get the superconductor floating, you need about 1/2 a tesla magnetic field, otherwise, the weight of the superconductor will overpower the levitation effect.
@WOWLab Well, we (my friends and I) were thinking os making small coils close to each other in order to generate a strong enough magnetic field. Just to illustrate, how "big" is a 1/2 Tesla field?
At least, that's waht the professor who is helping us said. He also said that making the track out of magnets would be quite unstable because they are not exactly the same and the field generated would be "wacky"...
pardon me for interfering. this is for personal knowledge.
could you please clarify that the china maglev employ magnets for rails while the superconductor is created inside the train base? i guess it'd be impracticable the other way.
@WOWLab Really cool track! But it's flat, i.e. in 2 dimensions.... See a video of such a levitating train in 3 dimensions here: moebius dot youtube dot mosem dot eu ;-)
a magnet have no poles. what is called the north and south pole of the magnet is only determined in the presence of another magnet. the flow of electrons inside a magnet moves in doughnut shaped loop. its hard to explain. the loop is circulating like a vortex. when you determine the polarity of a magnet with another magnet it attracts in one direction because the spin of the magnetic field of both magnets are spinning in the same horizontal direction. when magnets repels one spin in opposite.
all conductive materials structure is a bit random. when electron motion passes trough it the material behave like light reflecting of a wall. the charge motion get scattered and you get lots of electron collisions (friction). the colder the material gets the fewer electron collisions the more electrons can move freely and the lesser the property (electric resistance) change. in a magnet the electrons move freely. when a magnet get close to a diamagnetic material it induces an opposing flow.
Oh, by the way... Do you think the magnets on the floor could be moved to make a different track? Or would it just fail? Think it would work... But I'm probably wrong :D
Ahh... That explains the 'smoke'! Liquid nitrogen... Cool. I once put a marshmallow over a tube thing with liquid nitrogen... Froze to the center in five seconds :D Tasted awesome! Mmmm... Marshmallow ice cream... ;D
How do you make the corners of the track? The magnets I am using are very strong and will not leave space between them. Also, what glue did you use to hold the magnets of the track down?
I READ THAT THE US WAS BUILDING A MAGNETIC TRAIN, BUT ONLY THIS ONE FLOATS INSIDE MAGNET RINGS,..SO ITS SUPENDED INSIDE THE RINGS ,..ALSO THE TRAIN SINCE ITS FLOATING INSIDE THE RINGS WILL HAVE SCREW FORM THAT WILL MAKE IT FASTER..
great video... i can understand the magnetic Levitation and Tunnel thingie.... but wat make them go forward... are you flowing any current throw it.... ???? and wat about breaks.... ???
So, was the BSCCO used on the train? I thought only YBCO worked on the trains? Oh, and also did you make the superconductor, since there are nearly no company that sell superconductors, other than the ones in kits. Please answer...
@crapbagprincess 1: the only two options are probably YBCO or BSCCO since their transition temperatures are above that of liquid nitrogen . 2: see 1. 3: You'll need a dewar or a Styrofoam thermos to keep it liquid for any length of time. Have fun!
Problem is, I could NOT get a hold of superconductors where I live.
It was practically impossible, the only remaining option was having them shipped and it would have taken way too long :( So I don't think I can do it...
@nambinhvu Keeping it cold? Liquid nitrogen. The magnets? Well, how about we make a limit for hovering cars? Such as... One, perhaps? Isn't that enough?
Yes it could but there is one Major and Highly Expensive Problem. How would you install these magnets in Roads or today? it would cost Billions Globally. Unless we started over again and build new Roads for these types of Car. Also what about the cold gas emitted from the LN? wouldn't it make vision through the scream nearly impossible?
@LeotheCool98 Nah, before we see such applications, there are always two other groups interested in trying new technologies: The military and the sex industry. So we should much earlier see either levitating tanks or... or...
@LeotheCool98 I doubt floating cars would be able to be made like this. Because then anyone who has any iron on them will have it torn from their bodies.
@prathammojo008 Usually physics or chemistry departments at local universities should have supplies of LN. LHe might be harder to get since it's quite expensive. You'll need a dewar to safely store the cryogenic fluids as well.
@jh014809 Good questions. In response: 1) The wider the track, the more stable the train is as it goes around the corners. We've made versions with 3 magnets, but the 4 magnet track just worked better. 2) You're right about the discrepancy in the animation. Nonetheless, it doesn't really matter how wide the SC is. 3) Underneath the magnetic track is a sheet of steel. Each set of NSNS magnets is stuck to the sheet via magnetic attraction. This force is strong enough to keep them in place.
1) How strong should the magnets be and whats the size( is it possible to this same thing with smaller magnet(10 in row)) 2) how much weight this force can lift 3) how much speed train might lost in curves
@Blackgaia123 1) Probably. You might need to make some friends at a nearby university but it shouldn't be too hard to get. Storing for more than a few hours is tricky however, since you'll need a special dewar to keep it liquid. 2) Superconductors can be found from various sources on the internet. They usually cost about 30-50 dollars for a piece about as big as a quarter. 3) You bet!
It is a realy nice animation, but it is wrong. There are two different kinds of superconductors, type I and type II. Your superconductor is the secound type and does not displace the magnetic field out of its volume. It holds the magentic field with flux tubes, this is called "Schubnikow-Phase". Please refer to literature, it is very difficult to explain - maybe you can correct the animation!
@bifi0310 You're right it is a type II SC, (as mentioned at 0:51). However, these type II SCs still exhibit the Meissner effect (ME). It's only above a critical magnetic field that the B-flux will penetrate the surface. I don't think we are using strong enough magnets to reach this field strength, so I expect the ME based explanation to hold in this case. Essentially, flux pinning may occur, but its contribution is likely to be a small compared to the ME. Thanks for the suggestion though.
1) How long can the liquid nitrogen keep the anti-magnets (sorry I forget it's name) at -166?
2) Can you make a bigger version of this? (Enough to fit people)
3) How much of the train would have to be filled with Liquid Nitrogen Canisters?
4) Couldn't you simply put a fan or some sort of other way for the vehicles to move without a push? (I realize that these models may have been too small)
@PotatoSol 1) about a minute 2) maybe 3) hard to say 4) sure, as long as the fan has no magnetic metal parts in it, otherwise some bad stuff might happen.
The reason it moves forward is that the levitation gives it an almost if not frictionless track, and when they tap it it will go, until it all of the liquid nitrogen evaporates causing it to heat up past -166 C.
@sharki11 You're absolutely right. There's no reason why the tunnel will make it move forward. But, there's so little friction that just the slightest push will make it go 'round and 'round and 'round... Also, if there's any slope on the track, then it will 'roll' down hill, so to speak, like the car does towards the end of the video.
@mefreebiejeebie I think it's dangerous if someone falls on train tracks no matter what they're made of. (I've put the magnets on my head and never noticed any negative side-effects.)
Belive it or not Free energy is real,But the Big corporations spend millions to ensure that information does not spread to the masses,Find the real deal, a free energy device at LT-MAGNET-MOTORdotCOM ,Let the revolution begin!
@juliesses Hey there - turn that frown upside down. Expensive trains are fun. They provide jobs and it's not like the ones with wheels are free either... Also, liquid nitrogen is cheaper than bottled water. (But it doesn't taste very good)

@crapbagprincess Thankyou for replying :)
Problem is, I could NOT get a hold of superconductors where I live.
It was practically impossible, the only remaining option was having them shipped and it would have taken way too long :( So I don't think I can do it...

@WOWLab Doubt it haha how would we get all those magnets and how would we be able to keep the superconductors cold in a life sized car :P

@nambinhvu Keeping it cold? Liquid nitrogen. The magnets? Well, how about we make a limit for hovering cars? Such as... One, perhaps? Isn't that enough?

Yes it could but there is one Major and Highly Expensive Problem. How would you install these magnets in Roads or today? it would cost Billions Globally. Unless we started over again and build new Roads for these types of Car. Also what about the cold gas emitted from the LN? wouldn't it make vision through the scream nearly impossible?

@LeotheCool98 Nah, before we see such applications, there are always two other groups interested in trying new technologies: The military and the sex industry. So we should much earlier see either levitating tanks or... or...

@LeotheCool98 I doubt floating cars would be able to be made like this. Because then anyone who has any iron on them will have it torn from their bodies.

prathammojo008 1 year ago
@prathammojo008 Usually physics or chemistry departments at local universities should have supplies of LN. LHe might be harder to get since it's quite expensive. You'll need a dewar to safely store the cryogenic fluids as well.

Loved the video. It's the only video on youtube that managed to explain how this actually works. Just a few questions though...
1 Why make the rail 4 magnets wide? Does it need to be like that?
2 Does the superconductor have to be that wide? 'cause at 1:20, it seemed a lot smaller than the actual superconductor at 0:35.
3 If the magnets are all arranged NSN, is there something to hold it longways, since they would repel each other?
Please answer
jh014809 1 year ago
@jh014809 Good questions. In response: 1) The wider the track, the more stable the train is as it goes around the corners. We've made versions with 3 magnets, but the 4 magnet track just worked better. 2) You're right about the discrepancy in the animation. Nonetheless, it doesn't really matter how wide the SC is. 3) Underneath the magnetic track is a sheet of steel. Each set of NSNS magnets is stuck to the sheet via magnetic attraction. This force is strong enough to keep them in place.

Hello!
I have some questions about this levitation.
1) How strong should the magnets be and whats the size( is it possible to this same thing with smaller magnet(10 in row)) 2) how much weight this force can lift 3) how much speed train might lost in curves

i have a couple questions
1.would an average joe student be able to get ahold of liquid nitrogen?
2.how much would a superconductor cost/where could we get it
3. what happens if u shove the trian really hard? does it go off the rails??
Blackgaia123 1 year ago
@Blackgaia123 1) Probably. You might need to make some friends at a nearby university but it shouldn't be too hard to get. Storing for more than a few hours is tricky however, since you'll need a special dewar to keep it liquid. 2) Superconductors can be found from various sources on the internet. They usually cost about 30-50 dollars for a piece about as big as a quarter. 3) You bet!

It is a realy nice animation, but it is wrong. There are two different kinds of superconductors, type I and type II. Your superconductor is the secound type and does not displace the magnetic field out of its volume. It holds the magentic field with flux tubes, this is called "Schubnikow-Phase". Please refer to literature, it is very difficult to explain - maybe you can correct the animation!
bifi0310 1 year ago
@bifi0310 You're right it is a type II SC, (as mentioned at 0:51). However, these type II SCs still exhibit the Meissner effect (ME). It's only above a critical magnetic field that the B-flux will penetrate the surface. I don't think we are using strong enough magnets to reach this field strength, so I expect the ME based explanation to hold in this case. Essentially, flux pinning may occur, but its contribution is likely to be a small compared to the ME. Thanks for the suggestion though.

FUCKING MAGNETS...HOW DO THEY WORK?
jtfunkymojo 1 year ago
Couple of questions:
1) How long can the liquid nitrogen keep the anti-magnets (sorry I forget it's name) at -166?
2) Can you make a bigger version of this? (Enough to fit people)
3) How much of the train would have to be filled with Liquid Nitrogen Canisters?
4) Couldn't you simply put a fan or some sort of other way for the vehicles to move without a push? (I realize that these models may have been too small)

Are you idiots?
The reason it moves forward is that the levitation gives it an almost if not frictionless track, and when they tap it it will go, until it all of the liquid nitrogen evaporates causing it to heat up past -166 C.

Just because the superconductor stays in the "tunnel" why should it mean that it moves forwards?
sharki11 1 year ago 2
@sharki11 You're absolutely right. There's no reason why the tunnel will make it move forward. But, there's so little friction that just the slightest push will make it go 'round and 'round and 'round... Also, if there's any slope on the track, then it will 'roll' down hill, so to speak, like the car does towards the end of the video.

A train with superconductors is the super easy part, vacuum insulated and tanks of LN2 would get the job done for cheap.
The problem is the powerful permanent magnets needed... could use electromagnets but that's suck a huge amount of power.
HWGuyEG 1 year ago
@HWGuyEG ...unless the electromagnets are made with superconductors, then power loss -> 0.

An expensive solution to an expensive problem... at least not a resource limited one.
Although... that'd work great with supersonic trains in vacuum tunnels.
