摘要
通过对处于变化外磁场中的圆柱形电容器的定性讨论和定量计算 ,把电磁场的角动量这一较为抽象的概念具体化 ,分析并论证了电磁场确具有角动量 ,且可与机械角动量相互转换 。
The abstraction of angular momentum of electromagnetic fields is concretized through qualitative analysis and quantitative calculation for a cylindrical capacity in a varying electromagnetic field. It has been shown that angular momentum exists indeed in an electromagnetic field and can be transformed mutually with mechanical angular momentum. And the conservation law is obeyed in process of transformation.
