Abstract

A numerical model for simulating high-Tc bulk material superconducting tapes subject to AC magnetic fields or transport currents, is presented. The model is based on an electromagnetic diffusion process and describes the superconducting tape as a nonlinear conductor with conductivity being a functions of both local magnetic and electric fields, as deduced from the flux creep E-J characteristics of the material. AC losses for various applied fields or transport currents are calculated and discussed.
