Abstract
We deal with the numerical approximation of a parabolic boundary value problem (BVP) with Neumann boundary conditions arising from the evaluation of transients in conducting ferromagnetic cores. This BVP is derived from the proper Maxwell equations. A nonstandard finite-difference (FD) technique is compared with a standard finite element (FE) formulation. For nonlinear problems, characterized by abrupt changes in the magnetic permeability, being the material coefficient in the BVP, the 2nd-order FD-scheme is recommended.
