✦ Synopsis

This paper presents a mathematica1 technique for determining the magnetic and electric field intensities and the current density in plane conducting metal plates of constant permeability produced by an external impressed alternating magnetic field. The fundamental Maxwell field equations are used as the basis of the analysis and expressions for the amplitudes of the fields and currents are written in matrix form. It is demonstrated how the field and current distribution may be simply and systematically determined in composite laminated plates such as those used in transformers by a simple matrix multiplication procedure.

The technique simplifies the calculations involving skin effect and magnetic shielding.
