ルギー積（ＢＨ）ｍａｘ−３５（ＭＧＯｅ）。In this invention, when the Fe-B-R magnet is magnetized at temperatures above 0°C, there is no difference in its magnetic properties from that at room temperature.
It is necessary to magnetize at a temperature below 0°C, and it is desirable that the temperature of the permanent magnet when assembling the magnetic circuit is as close as possible to the temperature at the time of magnetization. This effect cannot be obtained. In addition, excessive cooling than necessary will increase the magnetic field strength required for magnetization.
It is preferable that the cooling means be determined in consideration of the size of the Fe-B-R magnet, the workability of assembly, etc., since it is uneconomical. By the way, at room temperature, coercive force iHc = 12.5 (KOe), maximum energy product (BH) max-35 (MGOe).
