PURPOSE:To enable a superconductive magnetic circuit for transmitting alternate current magnetic flux which is easy to produce and has less alternate current loss to be made by forming a loop-shaped hollow vessel for a magnetic circuit using a cloth-shaped superconductive material by weaving the superconductive wire for alternate current with longitudinal and transverse strings. CONSTITUTION:With a superconductive wire for alternate current as a longitudinal and transverse strings 5 and 6, a superconductive material tape 7 with a width which is convenient for winding can be woven. On the other hand, an insulation loop-shaped hollow vessel forming material 8 is formed where it is formed by connecting a hollow straight pipe 8a and a hollow bent pipe 8b, a primary coil 2 and a secondary coil 3 with the required number of turns is housed and fixed within the straight pipe 8a or the bent pipe, and both edges of the coils 2 and 3 are pulled out of the pipe as connection conductors 2a and 3a. Then, while piling up a separately prepared insulation tape 9 which is wider than a superconductive material tape 7, for example a glass fiber tape and the superconductive material tape 7 and overlapping them 10 up to a required width, spiral winding around the entire length of the peripheral surface of the hollow vessel formed material 8 is made. It allows a superconductive magnetic circuit with low alternate current loss to be constituted. |
