摘　　要：针对磁场变化时激发产生的感生电场很难演示的问题,设计了演示感生电场存在的实验.该实验将不同功能的仪器组合起来使用,通过亥姆霍兹线圈的交变磁场对带电粒子的作用效果,直观说明感生电场的存在.The difficulty of producing a strong and persistent induced electric field makes it not easy to validate its existence. In this paper, some instruments with different functions are combined, and by using the motion of charged particles in the alternating magnetic field produced with Helmholtz coils, the existence of the induced electric field can be validated directly and easily.
