摘要
推导了铁磁体的磁矩公式,结合磁偶极子模型设计了一种分离铁磁体感应磁矩与剩余磁矩的测量方法.该种测量方法预先通过测量计算出铁磁体的感磁因子与剩余磁矩,之后只需要测量作用于铁磁体的外磁场就可以分别计算出铁磁体的感应磁矩与剩余磁矩.设计了实验测量方法,并用一个长方形铁磁体式样为例进行了实验测量,结果表明,该种测量方法精度超过80%.
First of all,the magnetic moment of ferromagnet has been derived and a method has been put forward to separate inductive magnetic moment and residual magnetic moment of ferromagnet.According to the method,it can separate the moments by measuring the external magnetic field after getting the value of inductive coefficient and residual moment through experimental measuring.At last,an experiment has been designed which uses a cuboid-ferromagnet as an example.The experimental result has showed the precision of the method is over 80%.
