Thanks! That website is useful. Now I know what they use, I can explore that a little more.

I thought the German trains used ferromagnets, but the Japanese trains use superconducting materials to create electromagnets. Please can you let me know if I'm mistaken.

Thanks Thanks for your help. It is really useful!

I'm interested in the superconductors they use to levitate trains. One of the most talked about high-temp-superconductors seems to be Ytriuum Barium Copper Oxide. I know this has a critical temperature of around 90-93K. Does anyone know any of its mechanical properties, such as Young's Modulus...
