PROBLEM TO BE SOLVED: To provide a light magnet for generating a high magnetic field without necessitating any special heat treatment furnace at the manufacturing of a magnet.
SOLUTION: Reinforcing and stabilizing superconductive wires constituted by using reinforcing and stabilizing materials for stabilizing materials covering a compound system superconductor are used for the winding of an electromagnetic coil. It is preferable that the compound system superconductor is made of tin niobate or made by adding titanium or tantalum to this. The reinforcing and stabilized materials are made of copper niobate or aluminum dispersed copper or the like. Thus, a magnet can be manufactured by applying epoxy resin while operating winding tension by a react-and-wind method by using the wires.
