PURPOSE:To heat-treat the title magnet at a high temperature and to enhance its superconducting property by a method wherein an inorganic high-melting- point material is laid between glass-insulated superconducting wires. CONSTITUTION:A glass-insulated superconducting wire 3 is formed after an oxide superconductor has been laid at a silver pipe and a rolled composite wire has been coated with a glass fiber 4. The wire 3 is wound on a bobbin 1; a winding part 2 is formed. During this process, an inorganic high-melting- point material 5 such as a silica fiber rope, a silica sheet or the like is wound between turns. A magnet which has been constituted in this manner is heated at 900 deg.C in the air; after that, it is impregnated with an epoxy resin 6 in a vacuum. Thereby, it can be heat-treated at a high temperature; its superconducting property is enhanced; its rigidity becomes sufficient. |
