Abstract
A magnet evaluating device evaluates an evaluation magnet by passing the evaluation magnet, which is formed by connecting a plurality of magnetic sections with insulating material in between, and a master magnet of the same form through an alternating magnetic field generated by an excitation coil, measuring the eddy current occurring in the magnetic section as voltage or current occurring in a detection coil and comparing the measured value for the evaluation magnet and the measured value for the master magnet.
