A current can also be induced by constantly moving a permanent magnet in and out of a coil of wire or by constantly moving a conductor near a stationary permanent magnet.
让永久磁铁在线圈中进出运动或让一个导体在固定的永久磁铁附近的区域移动，也会产生电流。

On the basis of the stationary state mathematical model of a PWM current-source converter, the paper analyzes the coupling of a converter and presents a simple decoupling feedforward control method.
An electrical current pulse applied to a thin conductive film heats the modulator section and the stationary phase within it, releasing a certain number of retained substances as concentration pulses.
