摘　　要：载流导线在磁场内运动过程涉及到的物理规律主要有:法拉第电磁感应定律,闭合电路的欧姆定律,安培力公式和牛顿第二定律,其主要的分析方法是利用牛顿第二定律列出载流导线在磁场中的运动方程,通过对问题条件由简到繁的逐步变化,分析讨论了载流导线在磁场内的运动规律.The movement of the lead carrying electric current in the magnetic field mainly concerns following rules of physics： Faradic law, Ohmic law of closed circuit, Formula of Ampere force and Newtonian second law. The primary analytical method of above - mentioned movement is deriving the motion function of the lead carrying current in the magnetic field according to the Newtonian second law, hence discussing the lead＇s motion pattern through gradual transformation of the conditions of the problem from easy to difficult.

关 键 词：载流导线 感应电动势 安培力 加速度 平衡速度
