对运动导体在磁场中切割磁力线产生动生电动势的讨论

Discussion on How The Electromotive Force Is Generated By Separating The Magnetic Lines for Moving Conductors In the Magnetic Field

本文揭示了动生电动势的实质,阐述洛仑兹力的两个分量总功为零,保持洛仑兹力不做功的性质。用能量的观点分析了在产生动生电动势过程中,洛仑兹力仅起到能量传递作用,把外力所提供的能量怎样转化为动生电动势的能量。

This paper reveals essence of the mobile electromotive force,stating the pro- perty that the algebraic sum of the work two branch guanta do in Lorenz Force is zero and that Lorenz Force itself can't do work。It indicates that the mobile eleetro- motive fore,Lorenz Fone only plays the role of conducting energy and converts into the energy of the moble electromotive fore the energy provided by the external force。
