To obtain the accurate magnetic properties of Nd-Fe-B sintered magnets with high coercivity (HcJ), we have compared a pulsed-field magnetometer (PF) method with a hysteresis graph (HG) method using an extra large-sized electromagnet. To prevent the effects of machining on magnetic properties in small samples when making measurements of the accurate hysteresis and demagnetization curves, cylindrical samples used in the experiment were kept at a constant common diameter of 10 mm. This was… CONTINUE READING
