| 摘 要： | 原子核外电子在外界磁场作用下的轨道运动会对高速运动的电子磁矩产生一个反向的作用效果,从而导致物质具有抗磁性等宏观效应。那么在电动机的感应线圈中为什么没有类似的现象呢？这是大学物理教学过程中,很多学生比较疑惑的地方,这里我们通过分析这两种模型,做一个简要说明。

| Abstract: | When the electrons circle the nucleus in a constant orbit under an outside magnetic field,it will have a reverse effect on the electronic orbit magnetic moment of the high speed movement electrons,which may lead to diamagnetism,and so on.However,in the induction coils of a electromotor similar phenomenon：why not This is the college physics teaching process,many students are more doubt place,here we through the analysis of these two kinds of models,make a brief explanation. |
