  • A Study on Magnetic Properties of an Anisotropic Magnetic Material
    榎園正人; 祖田直也, Lead, Recently, an attention has been paid to the study on Magnetic properties of materials subjected to the two-dimensional excitation. In the numerical approach to properties, some methods have been proposed, however, the complete method in common problems has never been built up. In conventional magnetic measurement of an anisotropic magnetic material, only the same components of the magnetic flux density B and the magnetic field intensity H in the excited direction are measured. The conventional measurement values have been dealt with as scalar variables. Since it is well known that B and H have a phase difference in material, it should be treated as vector variables. Accordingly, in this paper, we first define the effective anisotropic field, and then we carry out a finite element analysis taking into account the effective anisotropic field.
