  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.
