Abstract

The magnetic properties of an anisotropic, epoxy resin bonded magnet made from Magnequench powder of MQA-T type was investigated. The reversible magnetization processes and the magnetic parameters were examined by measurement of virgin magnetization curve, the major and minor hysteresis loops using a VSM mounted in a 14T electromagnet and the LakeShore VSM mounted in a 2T electromagnet. The coercivity and remanence versus the maximum magnetizing applied field were determined. As it results from the virgin magnetization curve shape and the field dependence of coercivity the magnetization reversal mechanism appeared to be the pinning one.
