稀土元素钕制的永磁体磁性很强但价格太贵,难以推广使用.不过,新型制造工艺可能会使这种磁体价格与普通铁磁不相上下.一种制造钕磁体的新型工艺将使电动机与电动执行机构发生天翻地覆的变化,这些电机与执行机构用在机床、机器人、办公机械、汽车电源附件和其他各种电力设备中.用这种新方法制得的产品可能是磁力最强的磁体,其磁场强度达4千万奥斯特以上,这一数值 The rare earth neodymium permanent magnet is very strong magnetic but the price is too expensive and difficult to promote the use of However, the new manufacturing process may make the magnet price comparable with ordinary ferrite.New neodymium magnets manufacturing process will make the motor And the electric actuator changes under the covers, these motors and actuators used in machine tools, robots, office machinery, automotive power supplies and other various electrical equipment. Using this new method of production may be the most powerful magnet , The magnetic field strength of 40 million Oersted above this value
