摘　　要：根据动生电动势中包含的矢量混合积,分析动生电动势的几何意义.在此基础上,对导体在磁场中运动产生的动生电动势用动生电动势的定义和求体积的方法进行求解,并从几何意义上对导体在磁场中运动时不产生动生电动势的情况进行说明.According to the vector hybrid product involved in the motional electromotive force, we analyzed the geometric meaning of motional electromotive force. On this basis, we solve emotional electromotive force produced by moving conductor in the magnetic field with the finition of motional electromotive force and the method of cubature. In addition, we explain e case that there is no motional electromotive force produced when the conductor moves in the magnetic field.
