<p>Provided is a method of identifying coercive force of a coercivity distribution magnet capable of accurately identifying the coercive force at each of the portions within the coercivity distribution magnet without cutting the coercivity distribution magnet to pieces, thereby providing a guarantee of high quality. The method of identifying coercive force comprises: a step of virtually setting a plurality of planar division domains with respect to an arbitrary plane of the coercivity distribution magnet, assigning the domains to a reversed magnetic field applying device while deploying a specific detector to each planar division domain, and creating a demagnetization curve; a step of identifying the minimum coercive force and an average coercive force from the demagnetization curve; a step of creating a coercivity distribution graph using three hypothetical items; and a fourth step of identifying a coercive force at a position within the plane in the coercivity distribution magnet using the coercivity distribution graph which is identified for each planar division domain.</p> |
