Abstract

Eddy current distributions on a thin conducting plate are solved by an integral equation method using edge elements. The normal component of eddy current density across the edge of triangular element is chosen as the unknown variable. In this paper, the authors investigate how to define the set of unknowns. The tree and co-tree of surface eddy current paths are introduced. The unknown surface current densities are defined on the paths of the co-tree and the zero divergence condition is applied to those of the tree. The proposed method is applied to a simple computation model in order to verify the applicability of the method
