無方向性電磁鋼板における透磁率テンソルの評価法に関する検討

抄録

　In this paper, we will suggest new evaluation method for expressing relationships between magnetic flux density and magnetic field strength. The calculate equation is suggested in order to consider the amplitude and phase of permeability waveform. Although nondiagonal term of permeability tensor is nearly zero under the alternating magnetic flux condition, it has a value under the rotating magnetic flux condition. We will estimate the magnetic field strength vectors at arbitrary direction by using the permeability tensor waveforms. The estimated results under the alternating magnetic flux condition have same tendency in comparison with the measured results. However, the results under the rotating magnetic flux conditions differed because the nondiagonal term of permeability tensor having values.
