1. A carrying apparatus comprising:

  • a track path having a track surface;

    magnetic field generating means, provided along said track surface of said track path, for generating, along said track surface, a magnetic field having a predetermined magnetic flux distribution pattern in a direction perpendicular to an extending direction of said track path;

    a carrier movably arranged on said track surface of said track path;

    at least one superconductor element mounted in said carrier, said superconductor element trapping a magnetic flux of a magnetic field applied during transition from a normal conducting state to a superconducting state and supplying a levitating force and a guide force acting in a direction perpendicular to the extending direction of said track path to said carrier by a magnetic force generated between the trapped magnetic flux and the magnetic field generated by said magnetic field generating means; and

    propelling means for supplying a moving force to said carrier in a direction of said track path in a non-contact manner.
