电磁场量和电磁力的相对性

THE RELATIVITY OF ELECTRO－MAGNETIC FIELD AND ELECTRO-MAGNETIC FORCE

本文从相对论的观点出发，由 Ｍａｘｗｅｌｌ方程导出了不同的惯性系之间电磁场量的变换关系，从而解释了Ｃｏｕｌｏｍｂ力与Ｌｏｒｅｎｔｚ力的本质，并讨论了电磁感应问题。

This paper the idea of theory of relativity and the Maxwell equation to deduce the transform relation of electro-magnetic field in different inertial frame. Thus it explains the essence of Coulomb force and Lorentz force,and discusses the problem of electro-magnetic induction.
