Abstract :
A simplified domain structure model (SDSM) is developed as a building block with which to construct a physical macroscopic magnetization model exhibiting pinning-type hysteresis. The pinning field is represented by a stop hysteron. The proposed SDSM represents the vector magnetic property of a silicon steel sheet qualitatively. A preliminary analysis of the magnetization process described by the assembled SDSMs is reported, where the local demagnetizing field reduces the coercive force.
