Experimental setup for synchronized surface and magnetic loss studies of grain oriented FeSi steel sheets
Abstract
We present technical details on an experimental setup that allows to measure magnetic losses in electrical steel sheets and the movement of magnetic domains on the sample surface simultaneously. The setup is suitable to investigate grain oriented electrical sheets in the polarization range 0.05 T to 2.3 T and at excitation frequencies between 50 Hz and 4 kHz. The screened surface area is 13 mm x 18 mm.
