Superconducting wires for persistent current switches and AC applications have a matrix of CuNi or mixture of CuNi and Cu. CuNi has high electrical resistivity and low thermal conductivity comparing with the properties of copper. Therefore, the thermal and the electromagnetic behavior of such wires during quench is apparently different from that of conventional copper-stabilized composites. To investigate these properties, we consider the effects of temperature gradient in radial direction of wire cross-section and the redistribution of currents at normal front in this paper.
