Eddy current losses due to alternating current strips

A two dimensional solution for the vector potential and eddy current loss in a plurality of conducting regions due to a plurality of current sources is presented. The solution is applicable to those problems with boundaries which may be aligned with the coordinate surfaces of an orthogonal system of separable coordinates. The vector potential solution and current sources are represented by a series of eigenfunctions and the boundary conditions for the fields are applied such that numerical techniques can be used in solving for the coefficients of the series solution and then the eddy current losses. The method is applied to the problem of currents parallel to conducting plates in rectangular coordinates and the results are compared to those of previous investigations.
