It is a common impression that the measured B(H) curves of permanent-magnet materials indicate the temperature and the operating point at which flux losses start to occur. As long as the operating point stays above the knee of the B(H) curve, no losses will be expected. The demagnetization process is, however, a time-dependent process and losses occurring… CONTINUE READING
