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.
The Shanghai maglev train or Shanghai Transrapid (Chinese: ä¸æµ·ç£æµ®ç¤ºèè¿è¥çº¿) is a magnetic levitation train, or maglev line that operates in Shanghai, China.
