电磁现象中,如果安培力做了功,则闭合电路(或通电导体)与磁场之间一定发生了相对运动,使电能与机械能发生相互转化,这就是说,安培力做功与电能及机械能的转化有对应的关系.一、安培力做功的实质大家都知道,导体在磁场中受到的安培力,实际上是导体内各定向运动电荷所受洛伦兹力的宏观表现,因此安培力对运动导体做的功也就与洛伦兹力对电荷的作用有关.安培力对导体做功(正功或负功)的过程,也就是导体内定向移动的自由
Electromagnetic phenomena, if the Ampere force to do work, the closed circuit (or through the conductor) and the magnetic field must have occurred between the relative movement of the electrical energy and mechanical energy mutual transformation, that is to say, Ampere work and electrical energy and mechanical energy conversion There is a corresponding relationship.Appel forceThe essence of work We all know that the conductor in the magnetic field by the Ampere force, in fact, is the conductor of the directional movement of charge Lorentz force suffered macro performance, so the Ampere force on the moving conductor The work done is also related to the effect of Lorentz force on the charge.Ampere force on the conductor to do work (positive or negative work) process, which is the freedom of directional movement within the conductor
