The Preisach model is constructed with some experimental loops that are measured to turn over at any external magnetic field to oppsite maximum one. It is possible to predict relations between magnetization and magnetic field, using the distribution function made from the experimental loops. It can think that the magnitude of distribution function imply the number of magnetic dipole in the magnetics. Therefore, it can expected that all values in the distribution function are positive. However, in the actual distibution function maken from the experimental loops, both areas having positive and having negative exist actually. In this paper, examples of adverse effects because of the large negative regions are shown. Then the moving model is applied as a solution of the problem. Predicted minor loops with the model are good agreement with experimental ones, confirming the effectivity of moving factor decided experimentally.
