Abstract
An apparatus for and a method of measuring permanent-magnet eddy-current loss is provided. A magnetic flux density measured in a Gaussmeteris fed back to a control device, and thus operation of a power supplyis automatically controlled. Accordingly, an experiment can be efficiently conducted. A non-magnetic and non-conductive measurement jigblocks heat generated in a permanent magnet sample from being dissipated to an iron core. Accordingly, eddy-current loss occurring in the permanent magnet samplecan be measured more precisely.
