Abstract
Several papers for eddy current analysis of thin conducting plates have been presented. The eddy current analysis is performed by an integro-differential method using a current vector potential. The integro-differential method is formulated for differential equation by a finite element scheme where the impressed magnetic flux density and the induced magnetic flux density are evaluated by integral terms. In this paper, a method for eddy current analysis of thin conducting plates taking account of the source currents in the conductor is proposed. A scalar potential is introduced for the analysis of source current distribution and the distribution of the scalar potential is calculated by a 2-D finite element method which is expanded to 3-D arrangement of the thin plates. The formulations for the current vector potential and the scalar potential are shown and the applicability of the proposed method is verified by using three computation models and an experimental model.
