用洛仑兹力说明安培力的机制

Showing the Mechanism of Ampere’s Force by Lorentz Force

对金属载流导体在磁场中分别处于静止、与电流方向平行运动、与电流方向垂直运动三种情况下,用洛仑兹力说明安培力的机制。一般金属导体安培力的经典微观机制是:由于洛仑兹力的作用,致使载流导体中的电荷重新分布,平衡时,整个导体系统所受内力之和为零,所受外力的合力就是载流导体在宏观上受到的安培力。

This paper is intcnded to show the mechanism of Ampere＇s force by Lorentz force when the metal conductor in the magnetization field is expatiated under three main headings, namely, rest, motion with the parallel direction of the current and motion with the uprightness direction of the current. The sutra microcosmic mechanism of the metal conductor Ampere＇s force is the Lorentz torce causes the redistribution of the electric charge in the conductor. When they are balanced, the internal force sum of the whole conductor is naught, the outside force sum of the whole conductor is Ampere force of the conductor in macroscopic.
