The anomaly factor that is the ratio of the measured eddy current loss to the classical calculated value tends to increase steeply when the thickness of non-oriented Si-Fe electrical steel sheets is decreased. To investigate the behavior of the anomaly factor in relation to the sheets’ thickness, magnetic domain observation was performed, using the Kerr effect. The grains of a thinned sheet exhibit a stripe domain pattern. Grains exhibiting a stripe domain on the surface had a closure domain structure in a cross section of a sheet. It was found that a field applied in the sheet plane induced a magnetization component normal to the sheet plane, which may increase the anomaly factor of thin sheets.
