Nonlinear magnetic field model by FEM taking into account hysteresis characteristics with M-B variables

The aim of this work is to describe a methodology for nonlinear magnetic field calculation applied on two-dimensional (2-D) finite element taking into account a static hysteresis model. The scheme is based upon the definition of modified governing equation derived from Maxwell's equations considering the magnetization M. The simulation results agree to experience with an Epstein frame and the numerical calculation by the Newton-Raphson method shows good convergence.
