Abstract

A critical study of the Jiles and Atherton Mean Field Model was done. to determine the validity of the modal, a tool in describing and understanding the magnetization process in textured silicon steels.Hysteresis loops were generated using an Epstein apparatus in various directions with respect to rolling and for various external magnetic fields. Various techniques of generating the loops from the model and analyzing the experimental results were proposed. These techniques were then used to obtain the model parameters.An analysis of the experimental data using this modal lets us conclude that the modal gives a close description of texture influence on hysteresis behaviour and predicts the variation of the pinning parameter k which agrees with our understanding of the role of texture in changing the parameter. We have observed that the highest value of this parameter coincides with the angles at which it is most difficult to magnetize the speciment.
