PURPOSE:To decrease leaking magnetic flux as much as possible and to achieve efficient transfer of magnetic force at a small loss, by surrounding a magnetic force transfer path with a superconductive material. CONSTITUTION:A magnetic force transfer path is composed of a superconductive material 5 and a ferromagnetic material 6. When a magnetic field H is applied to the magnetism transfer path from a magnetism generating means 1, a current flows through the superconductive material 5 so as to offset the magnetic field H. A magnetic field H' is produced at the opposite end of the magnetic force transfer path with the current 7 so that reverse polarity with respect to the magnetic field H, which is produced by the magnetic force producing means, is obtained. Thus, leaking magnetic flux is decreased as much as possible, and the efficient transfer of the magnetic force is achieved at a small loss. |
