On the relation between Ampere force and Lorentz force;
论安培力与洛伦兹力的关系
How to produce the formula of Lorentz force;
洛伦兹力公式是怎样给出的
According to movement example,analyse the Lorentz force woking whithin Ampere force working and motional electromotive force,then draw a conclusion that Lorentz force never work to the moving charge,but played the transmission energy role.
通过具体运动实例,分析安培力作功中与动生电动势产生中洛伦兹力的作功,得出洛伦兹力永不对运动电荷作功,但起到传递能量的作用的结论。
