1. A magnetic field analysis device comprising:
a processing device including a magnetization application unit and a magnetic field calculation unit, the processing device configured to:
divide, by the magnetization application unit, a virtual space into a plurality of volume elements and applies magnetization to each of the plurality of volume elements; and
calculate, by the magnetic field calculation unit, on each of a plurality of observation points in the virtual space, based on the magnetization applied to a portion of the plurality of volume elements around the observation point, a magnetic field generated at the observation point for each volume element and obtain a magnetic field generated at each of the plurality of observation points based on a calculation result of the each of the plurality of volume elements,
wherein the processing device, with the magnetization application unit, is further configured to
divide the virtual space into a plurality of voxels having the same shape and dimension,
apply magnetization to each of the plurality of voxels,
perform coarse graining for collecting a plurality of continuous voxels in a first direction to one volume element to make dimension relating to the first direction greater than dimension relating to a second direction and a third direction on at least a part of the plurality of volume elements, and
apply magnetization to each of the coarse-grained volume elements based on the magnetization applied to the plurality of voxels included in the each of the coarse-grained volume elements.
