ABSTRACT:
A superconducting magnetic levitation apparatus for driving a floating body efficiently and controllably, for producing a strong driving force, and for generating a lifting magnetic field having a uniform intensity in a running direction and producing a guidance force in a lateral direction, to stably run the floating body. The superconducting magnetic levitation apparatus includes a lifting magnet for forming a track, a floating body made of a high-T.sub.c superconductor, and a cooling device for keeping the floating body at a superconducting state. A plurality of coils are disposed on the lifting magnet, to be used as propulsion electromagnets, for generating a magnetic field necessary for running the floating body, with each of the coils being a flat, air-core coil, and with the coils being excitable by a polyphase alternating current.
