摘要：
A magnetic material is magnetized with a direct current to a rotational magnetization region and an alternate current excitation is performed in a direction having a component orthogonal to a direction of the direct current magnetization, and a component of an alternate current magnetic field which is generated by an interaction with the magnetic material in a direction orthogonal to the direction of the direct current magnetization is measured. Due to such a measuring method, a local magnetic property of the magnetic material can be measured with high precision almost without being influenced by disturbances or the like.
