Demagnetization curve, or BH curve is the second quadrant of hysteresis for hard magnetic materials including rare earth magnets. It provides information about the magnetic characteristics of a magnet, including the magnetic field strength and resistance to demagnetize. Especially the curve at high temperature provides important reference for engineers to calculate and find out the appropriate magnet material and grade to meet their working requirement. Therefore we hereby prepare you demagnetization curves at several high working temperatures for sintered Neodymium magnets and Samarium Cobalt magnets fore each available grade. Please click each cell for its demagnetization curves respectively.
