Abstract :
The paper presents a fast method for computing the quasi-stationary electromagnetic field in devices containing both magnetically nonlinear materials and hysteretic materials. The linear iterative procedure of fixed-point type allows the correct evaluation of the local field and of the losses produced by hysteresis and eddy currents. The tests are performed on a single-sheet device used to determine the magnetic material losses under the AC uniform field
