Abstract

In order to reproduce the experimental results of AC losses in a Bi-2223 Ag-sheathed tape exposed to the external magnetic field with an arbitrary angle to the broadest face, we calculate the AC losses by means of the two-dimensional finite element method that directly analyzes the magnetic field distribution around the wire. It is assumed that the voltage-current characteristics are represented by the power-law model including the dependence of both the critical current density and n-value on an effective perpendicular component of applied magnetic field. The obtained numerical results have a good agreement with the experimental results in the large amplitude of applied magnetic field.
