Abstract

We present the modelling of eddy-currents and surface electric charges created by an electromagnetic field in a conductor. We used an electrical field formulation in which a finite element method inside the conductor is coupled with an integral method for the outside. The induced current is then directly given by Ohm´s law. Multiply-connected domains are considered. The electric charges which appear at the surface of the conductor are calculated and capacitive effects are evaluated
