We present a recently developed magnetizationinterpretation method based on the analysisof both the semi-log and the linear magnetizationderivative responses [1]. We discussdiverse scenarios of soft magnetic materialsbased on a law of partial magnetizations formagnetic mixtures and on the Langevin-Weissmodel. An algorithm is proposed for fitting thephysically based model parameters using a deterministicapproach [1], [2]. We illustrate theproposed technique through a variety of wellmotivatedexamples covering isotropic/anisotropicand homogeneous/non-homogeneous materials:an isotropic soft ferrite, a nanocrystalline alloymagnetized transverse to its preferred direction, anon-oriented electrical steel, and a highly grainorientedelectrical steel magnetized transverse tothe rolling direction. Our method has demonstratedto simplify the analysis of soft magnetsenabling an easier and more accurate modelingof anhysteretic magnetization curves.
