摘要/Abstract

摘要：从特殊情况到一般情况推导出动生电动势的计算公式，证明了产生动生电动势的过程中总的洛伦兹力不做功，遵循能量转换与守恒定律，从而发现动生电动势产生的原因是洛伦兹力的一个分力提供非静电力，洛伦兹力在此过程中作为能量传递的工具.

关键词： 动生电动势, 洛伦兹力, 安培力, 非静电力

Abstract: The computation formulation of motional electromotive force was deduced under special and general conditions,and it was proved that the total lorentz force does not apply work in the course of generating motional electromotive force.Consequently,the reason of generating motional electromotive force is that a component of total lorentz force provides a non-electrostatic force.In the course of generating motional electromotive force,the energy conservation law is satisfied,and lorentz force acts as a implement of energy transfer.

Key words: motional electromotive force, lorentz force, amepere force, non-electrostatic force
