✦ Synopsis

The influence of dc transport currents on alternating-field hysteresis loss was investigated for a single core superconducting wire. The configuration of the sample coil simulates a tight solenoidal winding of superconducting magnets, and the field is a small transverse alternating field applied on top of a large dc bias. The losses were determined as a function of transport current and external field from simultaneous measurements of the magnetization and the dynamic resistance. The results were compared with calculations based on a slab model. When the parameter of the slab-equivalent of an array of superconducting wires is chosen properly, the calculations explain the observed results quite well.
