This paper describes a non-contact running system utilizing oxide superconductors and permanent magnets. The vehicle containing superconductors can travel on the rail with homogeneous magnetic flux density along the moving direction, using acceleration of electromagnetic induction. Three kinds of permanent magnets, Sm-Co, Nd-Fe-B and ferrite magnets, were attempted. Such a traveling is possible by being hang under the rail of Sm-Co and Nd-Fe-B magnets, due to strong pinning effect of the superconductor. The devision point for the direction of motion was also constructed on the rail of ferrite magnets by partially using electromagnets.
