“…The major drawback of this formulation is its large number of unknowns, since both involved quantities are vectors. For this reason, a penalty method is applied to eliminate one unknown and end up in one equation that only keeps the degrees of freedom of the magnetic field intensity [4]. The used perturbation technique needs a penalty factor that has to be chosen appropriately to obtain correct results.…”

This paper deals with the usage of a magnetic field oriented formulation that is derived from a mixed formulation using the penalty method, which reduces the problem to one equation. To achieve accurate results the ocurring penalty factor has to be chosen properly. For this reason, a rule to select this parameter is developed for linear and nonlinear material laws. It is shown that it yields good results when compared to measurements provided by the TEAM problem 13.
