Abstract
Abstract A superconductor for a pulsed magnet has a wire assembly including a plurality of superconducting wires individually bonded with a solder. The solder consists of an Sn-Pb alloy containing indium and/or bismuth. When this solder is used, a coupling current induced between the superconducting wires can be reduced to an acceptable value.
