✦ Synopsis
Analytic expressions for hysteretic loss have been developed for half-cycle and full-cycle field sweeps for rod geometries for a critical state model with critical current inversely proportional to field. Bulk effects with surface-like character are discussed along with surface shielding fields and the demagnetizing factor. The loss expressions of various models are compared to experimental loss data made on a series of Nb Ti superconducting wires. Universal loss curves constructed from experimental loss curves by appropriate normalization are obtained and used to predict loss accurately. Bias field ripple losses are also reported.
