Permeability tensor of grain-oriented silicon steel sheet

This paper deals with the numerical expression of the rational magnetic properties on a silicon steel sheet that are called two-dimensional magnetic properties. In the past, the magnetic properties were estimated by scalar values in the measuring direction under the condition of an alternating magnetic field excitation. These properties cannot exactly take into account the phase difference between the magnetic flux density B and the magnetic field strength H in the case of rotating magnetic field excitation. We therefore investigate the expression of the magnetic properties by using the permeability tensor. The calculated results by using the permeability tensor correspond to measured results very well.
