摘要：
The paper reviews formulations of three-dimensional eddy current problems in terms of various magnetic and electric potentials. The differential equations and boundary conditions are formulated to include the necessary gauging conditions and so to ensure the uniqueness of the potentials. Different sets of potentials can be used in distinct subregions, thus facilitating an economic treatment of various types of problems. As a novelty, the way of interfacing conducting regions with an electric vector and a magnetic scalar potential to eddy current-free regions with a magnetic vector potential is described. Finite element solutions to several large eddy current problems are presented. © 1990, IEEE. All rights reserved.
