1、The inverse effect also occurs: a spinning bar magnet will cause a suspended copper disk to rotate.
逆效應，也會發(fā)生：紡紗條形磁鐵將導致暫停銅磁盤旋轉(zhuǎn)。

2、If the bar magnet is simply held stationary near the coil, no current is indicated.
如果磁棒單純靜止在線圈附近，就檢測不到電流。

3、Magnetism of the bar magnet is produced by the surface molecule electric current.
磁塊的磁性，是由磁塊的表面分子電流產(chǎn)生的。

4、The magnetic state of a bar magnet or a horseshoe magnet is extremely complicated.
條形磁鐵或馬蹄形磁鐵的磁態(tài)是極其復雜的。
