Estimation of the critical current of CORC® conductor using the measured magnetization losses

Since CORC (R) (Conductor on Round Core) is made of multiple strands of a superconducting tape to conduct a large current, it is difficult to measure the critical current due to the limitation of a capacity of a power supply. The magnetization loss of a superconductor is dependent on the full penetration field. The full penetration field corresponds to the inflection point of the magnetization loss graph with respect to the external magnetic field. We propose a method to predict the critical current of CORC (R) indirectly. This method uses the measured magnetization losses of various CORC (R) samples for the prediction of the critical currents.
