Abstract
A magnetism measuring method includes magnetizing a magnetic material with a direct current to a rotational magnetization region, performing an alternate current excitation in a direction having a component orthogonal to a direction of the direct current magnetization, and measuring a component of an alternate current magnetic field generated by an interaction with the magnetic material in a direction orthogonal to the direction of the direct current magnetization.
