Abstract
A finite element formulation for ferromagnetic thin sheets carrying time-harmonic eddy currents is presented. The static field outside the sheets is described by a magnetic scalar potential on one side of the sheet and by a magnetic vector potential on the other side. Special interface conditions resulting in a symmetric finite element system matrix are developed to take account of the sheet. A simple example is presented to demonstrate the efficiency of the method.
