摘要
Magnesium diboride (MgB2) is a good alternative for some of the conventional superconductors due to its low raw material costs and to its relatively simple production process. MgB2 wires have also been considered for AC applications. In this work, we present the magnetization AC loss results of a Ti-sheathed monofilament MgB2 wire when magnetic fields are applied perpendicular to the wire axis. Losses were measured by the calibration-free method using a lock-in amplifier at 144 Hz and also investigated theoretically in the same condition. Numerically estimated losses were compared to measured values.
