A.由于磁场变而产生的电动势不是感生电动势; The electromotive force due to the change of magnetic field is not Induced Electromotive Force;
B.由于线圈(导体)动产生的电动势是动生电动势; The electromotive force produced by the coil (conductor) is Motional Electromotive Force.
C.由于磁场变而产生的电动势是动生电动势; The electromotive force due to the change of magnetic field is Motional Electromotive Force.
D.由于线圈(导体)动产生的电动势不是动生电动势; The electromotive force due to coil (conductor) mot
