@IndependentLiberty It can support a lot of weight, something like 10 times its own mass, but it will fall off the track easily if there is too much torque.

@FASELstudios You'd have to tilt the entire track in order to make that work, but yes, if you tilt the track the puck will accelerate.

@Epigeneticcode There is a lot of what is essentially magnetic friction -- it will still stop moving because of the joints in the magnets. This is because the magnetic field is not 100% uniform at the joints.

@Cryostar37 Superconductivity occurs at low temperatures, you need the liquid nitrogen to keep the superconductor cold. We have not yet discovered materials that can superconduct above 140 K.

@Baarsian There is magnetic drag on the superconductor, but it's not due to the ordinary electromagnetic induction effects, it is due to the energy required to move the pinned magnetic flux lines.

@bryan3184 I think I see. If you built it as you suggest, the magnetic field wouldn't be constant and the L would act as a brake and stop it completely. See our other video to see the brake.

@saloniSurana In order to get it to stay on the track you have to have enhanced flux pinning. This is not easy to accomplish, and also too long for a YouTube reply!

@enocon22 Great question. The scale will read 10kg + 100 g, the mass of the track AND the superconductor. It will read this when it is levitating and when it warms up, stops levitating, and falls to the track. Take physics in the 12th grade, and you'll learn exactly why this happens!

@danger2society78 No, the electrons in the wire wouldn’t feel a force. If it were a loop instead, they would move, but their movement would be miniscule – you wouldn’t get any current out of that loop.

@keildouglas It would eventually stop, but not because of air resistance. The joints in the magnets create a slightly non-uniform magnetic field which causes what's essentially magnetic friction inside the superconductor. This friction will slow the superconductor down.

@ksungjin10 It will jump the track eventually. It's not air resistance that slows it down, it's the joints in the magnets that cause magnetic friction. Removing air resistance won't have that much of an effect.

@MaximPodolsky We haven’t tried this, but your suggestion would work. We’d still need the motors, though, because it’s magnetic friction that slows it down and not air resistance.

@bryan3184 There is no maximum angle, but building a track that can turn 90 degrees would be impossible. So the problem is not with the superconductor but with the track. The maximum angle is dictated by the size of the magnets – the smaller the magnets the larger the sharper the turn.

@almightyon1 No, it's because the magnetic field from the magnets is not perfectly uniform. Each joint of the magnets means the magnetic field changes slightly. That causes essentially magnetic friction inside the superconductor.

@trev625 If the magnetic field were seamless -- made from one solid magnet -- we wouldn't need the Hot Wheels motor. Air resistance would slow it down, but the superconductor will warm up before air resistance could slow it down.
