<P>PROBLEM TO BE SOLVED: To enable evaluation of magnetic characteristics in a stress applied state. <P>SOLUTION: A sample piece is formed into a shape having a center part and the even number, i.e., 6 or more, of extended parts extending therefrom in a radial direction, and an axis passing through each set of the extended parts located in a diameter direction is set as a stress application axis. Stress is applied to this sample piece from at least three axial directions through stress application means. Then, the magnetic characteristics of the sample piece is measured in a stress applied state. Thus, the magnetic characteristics are evaluated in a stress applied state not only in a compression and tensile direction but also in a shearing direction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
