Abstract

AC losses are numerically evaluated for a Bi-2223 tape-shaped wire in combined alternating transport current and external AC magnetic field with a phase shift. It is considered that the external field is applied only parallel to the wide surface of tape. Since the multifilamentary wire without twisting is assumed, a solenoidal coil is simplified as a homogeneous superconducting sheet with infinitely wide surfaces. The electromagnetic quantities are numerically calculated by solving Maxwell's equations and the voltage-current characteristics represented by the power law simultaneously. The calculations of AC losses are carried out as a function of both amplitudes of transport current and external magnetic field. The obtained results are plotted on a master curve for the maximum magnetic field applied to the wire.
