Comparison of the classical and generalized Preisach hysteresis models with experiments

The authors describe the experimental testing of the accuracy of the classical and generalized (nonlinear) Preisach models of hysteresis. The experiments performed for two typical magnetic tape materials show that both models are about equally accurate when the reversal values of the magnetic field are larger than or equal to coercive field values. However, the generalized Preisach model gives more accurate predictions when the reversal values of the magnetic fields are smaller than the coercive values
