Abstract
This work presents an improved method to take into account magnetic nonline arity's in time-stepped two dimensional Finite Element calculations. A diff erential magnetic reluctivity tensor is employed. Also, in order to model t he nonlinearity Langevin function is used. Numerical convergence is faster than classical procedures.
