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。

If the bar magnet is simply held stationary near the coil, no current is indicated.
如果磁棒单纯静止在线圈附近，就检测不到电流。

This machine has a stationary block on which is cast in the form of a dead coil.
