“…Mechanical stress induced anisotropy energy density K an (σ) is given by the following equation [ 7 ]: where λ s is the saturation magnetostriction and φ is the angle between the magnetizing field direction and the direction of the stress. However, one should note, that the saturation magnetostriction λ s changes its value with applied mechanical stresses [ 8 ].…”

The paper presents results of validation of the anhysteretic magnetization model for a soft amorphous alloy with significant perpendicular anisotropy. The validation was carried out for the Jiles-Atherton model with Ramesh extension considering anisotropy. Due to the fact that it is difficult to measure anhysteretic magnetization directly, the soft magnetic core with negligible hysteresis was used. The results of validation indicate that the Jiles-Atherton model with Ramesh extension should be corrected to allow accurate modeling of the anhysteretic magnetization. The corrected model may be applied for modeling the cores of current transformers operating in a wide range of measured currents.
