Flux Penetration into a Wire of a Nonideal Type II Superconductor in a Transverse Magnetic Field

The quasi-static flux-distribution in a wire of a nonideal type II superconductor induced by a transverse magnetic field is discussed in terms of the critical-state model with the pinning force of the Bean-London type. The hysteretic loss per cycle caused by the variation of the transverse magnetic field is also calculated from the obtained expression on the flux distribution. In the present configuration, the flux motion is two-dimensional and the value of the hysteretic loss is appreciably larger than that caused by the cyclic variation of a longitudinal magnetic field, where the flux motion is one-dimensional.
