Evaluation of Electromagnetic Properties in HTS Wires and Coils Utilizing Two Finite Element Methods

Abstract

Electromagnetic properties in high temperature superconductor (HTS) wires and coils were numerically evaluated using two kinds of finite element methods. One is the method formulated using a self-magnetic field generated by a current induced in an analysis region. The other is based on current vector potential. First, governing equations for these methods are derived using Maxwell’s equations. After that, electromagnetic responses such as AC loss and screening-current-induced field carried out up to now by several groups including the author are reviewed for one- and two-dimensional HTS wires and coils.
