Minor Loops Calculation with a Modified Jiles-Atherton Hysteresis Model

Jean V. Leite, N. Sadowski, Patrick Kuo-Peng, Abdelkader Benabou


This work proposes a modification in the Jiles-Atherton hysteresis model in order to improve the minor loops representation. The irreversible magnetization component is slightly modified keeping unchanged the other model equations and the model simplicity. Differently to other proposed methodologies found in the literature, the previously knowledge of the magnetic field waveform is not need to assure closed minor loops. Measured and calculated hysteresis curves are used in order to validate the methodology.
