其實磁鐵能(neng)夠吸(xi)鐵磁(ci)(ci)性物質，原(yuan)(yuan)來高中(zhong)物理的(de)(de)(de)時候(hou)就曾講(jiang)過，電(dian)(dian)(dian)生(sheng)磁(ci)(ci)，磁(ci)(ci)生(sheng)電(dian)(dian)(dian)。而(er)(er)初中(zhong)物理曾講(jiang)過，定向移動的(de)(de)(de)電(dian)(dian)(dian)荷形(xing)成電(dian)(dian)(dian)流。而(er)(er)電(dian)(dian)(dian)流會產生(sheng)磁(ci)(ci)場。眾(zhong)所(suo)(suo)周知，物質是(shi)由分(fen)子(zi)(zi)(zi)(zi)組成，分(fen)子(zi)(zi)(zi)(zi)由原(yuan)(yuan)子(zi)(zi)(zi)(zi)構(gou)成，而(er)(er)原(yuan)(yuan)子(zi)(zi)(zi)(zi)可再分(fen)為原(yuan)(yuan)子(zi)(zi)(zi)(zi)核與(yu)核外電(dian)(dian)(dian)子(zi)(zi)(zi)(zi)，這(zhe)里(li)的(de)(de)(de)核外電(dian)(dian)(dian)子(zi)(zi)(zi)(zi)也就是(shi)上面所(suo)(suo)說的(de)(de)(de)電(dian)(dian)(dian)荷，它帶(dai)負電(dian)(dian)(dian)。一般情況下(xia)，核外電(dian)(dian)(dian)子(zi)(zi)(zi)(zi)有兩種運(yun)動狀態(tai)，一種是(shi)繞原(yuan)(yuan)子(zi)(zi)(zi)(zi)核旋轉，一種是(shi)自旋，可以看做類似(si)于地球(qiu)與(yu)太(tai)陽的(de)(de)(de)關系，但是(shi)微觀世界的(de)(de)(de)法則與(yu)宏觀世界并(bing)不相同，所(suo)(suo)以這(zhe)里(li)只能(neng)說類似(si)。
