摘要
通过对载流直导线外一个运动电荷在不同参考系中的受力情况进行分析,讨论了电作用与磁作用的内在关系,得出电场力和磁场力是统一电磁相互作用的两种表现形式,进而说明电磁场是一个协变的统一体。
This paper analyses the stress characteristics of moving electric charge along the long unlimited current-carrying straight wire in the different coordinate systems,and discusses the internal relations between electric force and magnetic force,thus gets the conclusion that electric force and magnetic force are two forms of the unified electromagnetic interactions.The conclusion shows that the electromagnetic field is the covariant unity.
