2-DIMENSIONAL STRESS MAGNETIZATION EFFECTS OF GRAIN-ORIENTED SILICON STEEL SHEETS

Changes in the magnetization vector due to tensile stress under a cons tant magnetic field for grain-oriented silicon-iron sheet strip sample s cut at various angles from the rolling direction have been investiga ted. In a low magnetic field, where the magnetization is less than 1.5 T, the magnetization vector lies in the direction of the sample lengt h and the magnetization decreases with the application of tension. Bey ond that magnetic field, the magnetization vector showed a two-dimensi onal hysteresis loop due to the application of tension. The maximum tr ansverse magnetization change appeared in a 10-degrees sample, where t he rotation angle of the magnetization vector was 2.5-degrees.
