Effect of Magnetic Hysteresis and Magnetic Anisotropy for Angle Difference between B Vector and H Vector

Abstract

The cause of angle difference between B vector and H vector (θ_BH) is made clear by means of numerical calculation taking into account of the magnetic hysteresis and magnetic anisotropy. Since the θ_BH, which is measured by the 2D magnetic vector property method, is usually ignored in the numerical calculation of electromagnetic field, it is our necessary to consider its effect on the numerical calculation. The research work says the θ_BH is possible to be expressed by the magnetic hysteresis phenomenon and the magnetic anisotropic phenomenon in numerical calculation of magnetic field. Therefore, the development to create the θ_BH model is not always necessary.
