Title:
SOFT MAGNETIC MATERIAL EVALUATION METHOD AND EVALUATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/119923
Kind Code:
A1
Abstract:
To make it possible to evaluate the magnetic properties, especially a variation in coercive force, of a soft magnetic material used in electromagnets at a stage prior to being assembled into electronic lenses and other products, this soft magnetic material evaluation method involves: imaging the surface of the soft magnetic material by using an imaging unit to acquire a crystal structure image of the soft magnetic material; processing the obtained crystal structure image of the soft magnetic material by using an information processing system to evaluate the variation in the coercive force of the soft magnetic material; and displaying information pertaining to the variation of the coercive force of the evaluated soft magnetic material on a display terminal.
