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.
Above is an image of the guideway for the Yamanashi maglev test line in Japan. THE MAGLEV TRACK. The magnetized coil running along the track, called a guideway, repels the large magnets. on the train's undercarriage, allowing the train to levitate between 0.39 and 3.93 inches (1. to 10 cm) above the guideway.
