Abstract :
A hysteresis curve of AC magnetostriction was measured, magnetizing a grain oriented silicon steel in the direction deviated from rolling direction of the sample. The AC magnetostriction curves were analyzed as harmonics in the interest of noise spectrum of such as a power transformer. The domain structure model in this magnetostriction process was proposed. The hysteresis was large in the magnetization direction inclined at 30 and 90° from the rolling direction
