High Temperature Superconducting (HTS) tapes are being proposed in the current transportation applications in electric aircrafts due to their capacities to carry large currents with low losses and higher efficiencies. Many systems are involved in the aircraft power distribution units and each component has its own magnetic field which may affect the working of surrounding systems. It has been found from many studies that perpendicular field has significant effect on the critical current of the HTS tape. In the present study, effort has been made to develop a numerical code through which magnetization AC losses due to external magnetic field are evaluated for YBCO superconductor. Calculated values are compared with Halse-Brandt model and it has been found that with the increase in the index value ‘n’, the results are approaching the Halse-Brandt model.
