Claim:
1. A magnetic measurement device for measuring remanent magnetization of a plate magnetic sample, the plate magnetic sample having a flat shape with a flat major surface and a magnetization direction perpendicular to the flat major surface, the magnetic measurement device comprising: a magnetic field generating part which comprises at least a pair of adjacent magnetic poles with different signs, and magnetizes said magnetic sample by the magnetic poles by applying a magnetic field and magnetizing a first region of the flat major surface of the magnetic sample in a first direction and a second region of the flat major surface of the magnetic sample in a second direction, the first direction and the second direction being perpendicular to the flat major surface of the magnetic sample and opposite to each other, and forming a boundary in the magnetic sample between the first region and the second region, the first region and the second region being adjacent to each other via the boundary; and a measuring part which measures the magnetic field of the magnetic sample magnetized by the magnetic field generating part and outputs the magnetic field as the remanent magnetization of the magnetic sample.
