Levitation. Maglev trains have no contacts with the rails while they move forward. They are levitated on the guide-way with the help of magnetic forces. Levitation is the process by which an object is suspended against gravity in a stable position without any physical contact.
This institute built a 40 km long track to test their Maglev in Yamanashi region, in Japan. It was on this track that the prototype MLX01 won the speed record for a train: 581 km/h. For efficiency reasons, the superconducting coils are placed on the sides of the wagons (four on each side).
