摘要
本文通过全电流定理证明了毕－萨定理．同时也证明了一段传导电流包括其激发的位移电流在内所产生磁场的安培环路定理总是成立的．
We have considered the possibility to apply the Ampere's Law to the analysis on the magnetic field of a straight conductor of finite length.Taking into account the charge accumulation on both ends,it is very reasonable to include the displacement current.We verify the Biot Savart Law by the Generalized Ampere's Law,and also show that the Ampere's Law is applicable to the analysis on the magnetic field both of the conductive current and of the displacement current.
