Abstract

PURPOSE:To easily produce magnetization pattern as required for an adhered magnetic body, by providing a superconducting material in a part of a magnetization yoke having winding and by energizing the winding with the superconducting material held in its superconducting state. CONSTITUTION:When a cooling agent 25 such as liquid hellium or the like is injected into a vessel 1, a superconducting material 15-19 on a magnetization yoke 4 becomes superconducting state. If winding 14 is energized with a high voltage and high current for a short period of time by a DC magnetizing power supply, magnetic flux produced in the magnetization yoke 4 magnetizes a principal magnet section 23 of a rotor 21, which becomes N and S poles alternately. Since the superconducting material 15-19 under its superconducting state shows dimagnetism due to the Meissner effect, the magnetic flux from the magnetization yoke 4 passes only the magnetized surfaces 10a-13a of poles 10-13 and therefore the principal magnet section 23 of the rotor 21 is magnetized in an approximately rectangular pattern. The magnetization yoke is provided with holes having a predetermined shape or with a predetermined number of holes and the superconducting material is arranged in these holes such that the superconducting material forms a part of the yoke. ln this manner, it is possible to apply any magnetization pattern as required for an adhered magnetic body.
