Abstract

A method that uses the magnetization M and the magnetic flux density B instead of using M and the magnetic field intensity H in the Preisach model is proposed. The Preisach distribution function and the Everett function obtained from M-B curves are compared with those of the conventional method. The former functions are much smoother than the latter, and this improves convergence and efficiency in computations because the slope of the M-B curves is lower than that of the M- H curves. A two-permanent-magnet system is analyzed as an example. The results are in good agreement with experiment. It is concluded that M-B variables are better than the M -H variables in the Preisach model for numerical analysis
