With the rise of interest in electric vehicles and wind generators, the demand for high energy permanent magnet has been increased. To evaluate the performance of the permanent magnets, the figure-of-merit, the energy product BH is widely used. However, the BH is often used without clear understanding of its definition, despite being a basic concept widely known to relevant industry workers and researchers. Basically, the BH corresponds to the energy stored in the stray field produced by the magnet itself. Consequently, it should be measured from H<sub>d</sub> and B at the remanent state, i.e., without any external field. Since the demagnetizing field depends on the shape of a magnet, the BH varies with the shape and thus, its value can be obtained from the remanent state in various shapes of magnet ... 전체 초록 보기
