Models of Magnetic Hysteresis Loops Useful for Technical Simulations Using Finite Elements Method (FEM) and Method of the Moments (MoM)

The paper provides the analyse of three simplified models of hysteresis loop suitable for technical purposes. Models consider the coercive field and utilize linear approximation with saturation, Langevin equation as well as arcus tangent functions. Validation of the models was done on the experimental data from measurements of magnetic hysteresis loops of four different materials. Accuracy of the models is assessed quantitatively. Finally, the parameters for practical application of the models are presented from the point of view different magnetic materials used in modelling by the finite elements method or the method of the moments.
