法拉第电磁感应定律的一般形式为(?)=△Φ△t,按照磁通量的变化原因的不同,通常有两种基本情况.一种是稳恒磁场中运动着的导体(导体棒切割磁感应线)产生的感应电动势,我们称之为动生电动势,设导体棒长为l,垂直于棒及磁场的速度为v,匀强磁场磁感应强度为B,有(?)1=Blv (1)另一种是导体不动(回路的面积一定),因磁场的变化而产生感应电动势,我们称之为感生电动势.设回路的
The general form of Faraday’s law of electromagnetic induction is (?) = △ΦΔt. There are two basic cases, depending on the cause of the change in the magnetic flux. One is a moving conductor in a stationary magnetic field (a conductor bar cuts magnetic induction lines) The induced electromotive force, which we call the electrokinetic electromotive force, is set as the length of the conductor bar, the velocity perpendicular to the rod and the magnetic field is v, and the magnetic intensity of the uniform magnetic field is B. There is (?) 1 = Blv (1) Another The type is the conductor does not move (the area of the circuit is certain), because of the change of the magnetic field to produce the induced electromotive force, we call it the induced electromotive force.
