摘要
从狭义相对论的角度出发导出了电流对运动电荷的电场力作用公式,揭示了电场与磁场可构成一个统一的实体——电磁场.
? The formula of electricforce,which acts on a charged particle with motion by the electric field of a steady current,is derived from the spcial relativity.It reveals the electric field and magnetic field constitute an unity as electromagnetic fields.
