Fabrication of uncontrolled magnetic levitation motor utilizing the diamagnetic magnetic force of bismuth

Abstract

Using the diamagnetic magnetic force of bismuth, the author succeeded in magnetic levitation in a non-controlled and non-rotating stationary state. Furthermore, by applying a rotating mechanism, it became possible to work as a non-controlled magnetic levitation motor. The author examined the placement of the permanent magnet that can float by experiment and numerical calculation and found the optimum combination of permanent magnet and diamagnetic material.
