Abstract

The authors deal with the four-component three-dimensional finite-element analysis of a flux concentration model with four thick conducting plates placed between a pair of AC-excited coils. An improved formulation that´s based on the Galerkin method is used. The distributions of flux densities, eddy currents and scalar potentials are calculated, and the results are discussed. The role of the scalar potential in the 3-D analysis is clarified. It is shown to be necessary when treating a model including conductors with any discontinuity or gaps in the streamlines similar to the flow of the impressed currents
