Abstract
A superconductive magnetic levitation apparatus is provided which is simple in structure, low in cost and is used for readily explaining superconducting phenomena such as the Meissner effect and the pinning effect. The superconductive magnetic levitation apparatus includes a levitation moving unit 5 including superconductors 4, and a heat insulative tank 51 for storing a coolant 52 for cooling the superconductors 4; and a track 3 arranged in confronted relation with the superconductors 4 of the levitation moving unit 5, the track 3 including a number of permanent magnets 2 fixed to a ferromagnetic metal plate 1. The permanent magnets 2 are composed of a plurality of series connected magnetic pieces having the same pole in a longitudinal direction of the track 3 and a plurality of parallel connected magnetic pieces having different poles in a transverse direction of the track 3.
