摘　　要：本文比较全面地分析了洛仑兹力和安培力的联系与区别,弥补了通常流行的讲联系多说区别少的缺陷,指出在任何情况下,安培力都是导体中自由电子所受洛仑兹力的一个分力——由电子相对于导线的平均定向移动速度所引起的力——的宏观表现。In this paper, the relation and the difference between Lorentz force and Ampere force are analysed rather completely . The common shortcoming of more studying on the relation and less studying on their differences is made up. The author suggests that, in any case, Ampere force is the universal behavior of one component of Lorentz force which the free electrons experience in conductor. This component is caused by the average directional movement of electrons in the wire.
