The symmetrical hysteresis loops of ferromagnetic core which made of non-oriented Si-Fe
3.2% wt can be seen in the Fig. 2. The magnetic flux distribution of the three limbed
ferromagnetic core can be seen in Fig. 3, at t=0.075sec.

core at t = 0.0075 sec.
The full paper will present the solution of this problem by using a 2D finite element method
with direct hysteresis handled by Fixed-Point iterative technique.
