Magnetic Hysteresis Loss Calculations of HTS Coil under Rotating Magnetic Fields

Abstract

We calculate magnetic hysteresis loss of HTS coil under rotating magnetic field. No transport current through the coil is assumed other than induced current. In order to find the frequency and applied field direction dependence of the loss, we present the loss versus applied field amplitude curves, for the frequencies f=1, 10, 100 and 1000 Hz, for seven different orientations of magnetic field. The hysteretic loss through the SC component increases with increasing frequency. This behavior is a consequence of higher field penetration to the tape at higher frequencies.
