Abstract

Transition in a superconducting coil is a much more complicated phenomenon than transition in a short superconducting sample since in the former the current and the magnetic field remain roughly proportional to each other and the local field may vary more or less independently, possibly with some discontinuities. The field distribution is such that every point of the superconductor is affected by different conditions, The cooling of a given turn may be quite different from that of another adjacent turn. The superconducting wires undergo various stages of magnetization from perfect diamagnetism up to complete paramagnetism. Consequently, the phenomenon encountered in a coil also involves a change in inductance resulting from a growth of transient or permanent resistive regions, separately or simultaneously.
