The experimental and simulative waveforms of magnetcurrent and DC bus current inosculate well, which indicates the validity of the proposed mathematical model of chopper and its control method.
Similarly, moving a magnet creates an electric current in a neighbouring wire.
同样，移动磁体也可以使线圈中产生电流。

The bullet has a small magnet inside that lets it generate AC current as it spins and a microprocessor that measures those current oscillations to derive how far it's traveled.
