A new modeling method based on the normal distribution of dipoles is used to represent the B-H loop of magnetic materials. The dipole representation can be expressed either in 2-orientation or 4-orientation. Depending on the accuracy required, the modeling method typically requires only magnetic saturation parameters, the critical H -field, and a few control parameters. Experimental results show that the method can be used to represent the B-H loop of materials very accurately.
