This paper presents magnetic properties of electrical steel sheets under DC-biased magnetization. We have prac-ticed measurement of the mixsing flux density between AC flux density and DC flux density (DC-biased flux density) by using the flux meter directly. The specimen was excited by voltage of sinusoidal, triangular and rectangular waves. When the amplitude of AC magnetic flux density was controlled to be constant, it was found that in the case of the rectangular exciting wave, that is, the smallest effective flux density value, the DC-biased flux density was lager than one of the other cases and the iron loss become smaller
