Abstract

PURPOSE:To make a permanent current flow-through a superconducting coil without a superconducting switch and a large capacity current source by forming magnetic flux in the constant orientation to the internal side after setting at least a part of the superconducting coil in a normal conductive condition and then removing magnetic flux after returning the coil to a superconductive condition in such a state. CONSTITUTION:A heater 4 is disposed in the vicinity of a superconductive coil 1. Moreover, a ball piece 2 of ferromagnetic material is disposed at the internal side of the superconductive coil 1 along the center axis thereof, a yoke 3 is disposed surrounding the external side of the superconductive coil 1 and a magnetic circuit is formed by these elements. A coil 5 is wound in the same axis as the superconductive coil 1. A power is supplied to the heater 4 to heat the superconductive coil 1 to turn to the normal conductive condition and a current is applied to the coil 5 or the superconductive coil 1 sandwiched externally by the magnets 6a, 6b for magnetization. Thereby, a magnetic flux B is formed in the center axis direction the internal side of of the superconductive coil 1 in the normal conductive condition. Supply of power to the heater 4 is stopped, the superconductive coil 1 is returned to the superconductive condition and the magnetic flux B is removed. Thereby, a permanent current flows through the superconductive coil 1 by electromagnetic induction.
