The magnetocrystalline anisotropy energy Ea is necessary to rotate all magnetic moments towards the direction of an external field (saturation). This texture dependent propterty is of special interest for electrical steels.
This example script is based on the followin literature: * Wu et al. (2017): Journal of Magnetism and Magnetic Materials 444: 211–217. * Bunge, H.-J.

Calculate anisotropy energy for different external magnetic field directions in sheet plane
Due to the rotation of an electrical motor the field direction is changing constantly inside the sheet plane.
