ELIMINATION OF MAGNETIC FLUX CAPTURED IN SUPERCONDUCTIVE MOLDING

摘要

PURPOSE:To obtain a condition without any magnetic flux finally captured by repeating operation for making them a superconductive condition again after two superconductive moldings are reciprocally made the superconductive condition once. CONSTITUTION:Two plate-like superconductive moldings 11, 12 are soaked in refrigerant 13 in a condition in which they are in contact with each other, cooled at critical temperature or less to make them a superconductive condition. The molding 12 is taken out from the refrigerant 13 to make it the superconductive condition once. The molding 12 is soaked in the refrigerant 13 again to make it the superconductive condition. Only that 17 which permeates a non-superconductive phase 16 of the formation body 12 in the magnetic flux 15 captured in the non-superconductive phase 14 of the molding 11 in the refrigerant 13 is captured in the molding 12. The same operation performed for the molding 12 is performed for the formation body 11. The magnetic flux of the moldings 11, 12 is reduced by repeating these operations. Thereby a condition without finally capturing the magnetic flux can be obtained.
