Abstract
The diffusion of electromagnetic fields under pulse excitation in ferromagnetic materials is investigated using finite-difference techniques. The nonlinearity of the magnetisation curve is taken into account, and special attention is given to high saturation. The diffusion in the semi-infinite space is studied for various waveshapes and for different field intensities. For electromagnets with rotational symmetry, flux-density distributions and eddy-current losses are computed.
