Hysteresis Losses and Effective Scaling Law for ITER Nb 3 Sn Strands

Hysteresis losses of five Nb3Sn International Thermonuclear Experimental Reactor reference strands were investigated by means of magnetization loop measurements in a vibrating sample magnetometer in a perpendicularly applied magnetic field. The magnetization loops were recorded while continuously sweeping the applied field between the extreme values ±Bm, covering a wide range of maximum applied fi...
