感应电动势是由于通过闭合导体回路的磁通量发生变化而产生的 .而导致磁通量变化的方式有两种 ,所以感应电动势可分为两种类型 :一是磁场不变 ,导体在磁场中运动 ;二是导体不动磁场在变化 .由前一种原因产生的感应电动势称为动生电动势 ,后一种原因产生的感应电动势称为感生电
The induced electromotive force is caused by the change of the magnetic flux through the closed conductor loop. There are two ways to change the magnetic flux, so the induced electromotive force can be divided into two types: one is that the magnetic field does not change and the conductor moves in the magnetic field; the other is The magnetic field of the conductor is changing. The induced electromotive force generated by the former causes is called dynamic electromotive force. The induced electromotive force generated by the latter cause is called induced electromotive force.
