Abstract :
The local correlation between the macroscopic numerical simulations and the microscopic experimental behavior of soft magnetic materials (Fe-Si sheets) is investigated. The 2-D and 3-D magnetic field computation involves finite edge-elements and a nonlinear model of the material. The experimental investigation uses the microscopic magneto-optical imaging for thin samples of magnetic material.
