PURPOSE:To utilize a low-resistance metal for a substantially low resistance stabilizer by suppressing a current due to the Hall effect generated in the metal to prevent the generation of excessive heat when the low-resistance metal is used as a composite stabilizer for a superconductive wire. CONSTITUTION:The boundary between a low-resistance metal (1) and a metal (2) combined for the purpose of reinforcing a wire rod is insulated except a part required for transfer of a current. When a current flows through a stabilizer placed in a magnetic field, an electromotive force is generated in the perpendicular direction to the magnetic field and the current. There is a difference in the magnitude of the electromotive force between the different metals, and a net electromotive force equivalent to a difference in an electromotive force between both metals operates along a loop crossing the boundary between both metals and a current is apt to flow in a loop-like manner. Since such a large loop is not limited in the shape, it may be considered in many ways, but any of them has at least one part which is cut off by intersecting an insulating part (3), so that a loop current crossing the boundary face may be prevented. |
