| Abstract: | The paper conducts some improvement on the electromagnetic induction phenomenon,self inductance with light emitting diode.Through the array form that is composed of some LEDS,mesimulate the direction of the direct current flow and demonstrate the process of charging and discharging capacity to make.Let the students know the direction of the current and understand the process,the process of charging and discharging capacity better.The experiment results are increased obviously. |
| Keywords: | LED electromagnetic induction self inductance simulation of the current flow direction demonstration of charging of capacity demonstration of discharging of capacity |
