Experimental testing of an anisotropic vector hysteresis model

A vector hysteresis model is experimentally tested for two soft magnetic materials in the two-dimensional case. The model expresses net magnetization as a sum of contributions from a number of pseudoparticles, each one having a dry friction-like hysteresis mechanism. Five adjustable parameters are used to represent hysteretic properties. Comparisons between calculations and measurements on silicon-iron are made for hysteresis curves and rotational and alternating hysteresis losses.
