摘　　要：在磁场中运动着的导体内产生的感应电动势称为动生电动势。鉴于学生在判定动生电动势方向时总是禁锢于课本的"左力右电"的判定方法,阐述了动生电动势的产生机理及五种判定动生电动势方向的方法。The electromotive force as the conductor moving in the magnetic field is known as the motional electromotive force.As the students are always locked in the conception of ＂left force,right electromotive force＂ when determine the motional electromotive force in the direction,five approachs to describe the direction of motional electromotive force are given in this paper.The aim is to enable students to break the shackles and sum up the knowledge learned before.

关 键 词：动生电动势 导体 方向
