摘要
本文研究了 Fe_(-24)Cr_(12)Co 和 Fe_(22)Cr_(15)Co_(-1)Si 两种永磁体的磁性与冲击和振动作用的关系,找到了影响规律,为在机械力作用下合理使用材料提供了实验依据。
The effect of batting and vibrating on the magnetic characteristic oftwo permanent magnets was studied.Experimental results showed that themagnetic characteristic was changed at the primary stage and was stabilized atfinal stage.The permanent magnet must be stabilized before its application.
