牽引(yin)電磁鐵可以被理(li)解為主要用來牽引(yin)機械裝置、開啟(qi)或者(zhe)關閉(bi)各(ge)種閥門，以執行自動(dong)控制任(ren)務。

常(chang)見(jian)的(de)(de)(de)牽引電(dian)磁鐵的(de)(de)(de)鐵芯都是軟磁性材料而制(zhi)，它(ta)的(de)(de)(de)作用顯而易(yi)見(jian)，如對電(dian)動機(ji)進行(xing)制(zhi)動以達到準確停車的(de)(de)(de)目的(de)(de)(de)叫制(zhi)動電(dian)磁鐵;

電(dian)(dian)(dian)磁(ci)(ci)(ci)繼電(dian)(dian)(dian)器(qi)(qi)和接觸器(qi)(qi)的(de)電(dian)(dian)(dian)磁(ci)(ci)(ci)系(xi)統、自(zi)動開關的(de)電(dian)(dian)(dian)磁(ci)(ci)(ci)脫(tuo)扣器(qi)(qi)及操作(zuo)的(de)被(bei)稱為自(zi)動電(dian)(dian)(dian)器(qi)(qi)電(dian)(dian)(dian)磁(ci)(ci)(ci)控制系(xi)統電(dian)(dian)(dian)磁(ci)(ci)(ci)鐵(tie)，還(huan)有(you)一(yi)類用于起(qi)重(zhong)裝置來吊(diao)運(yun)鋼錠、鋼材(cai)、鐵(tie)砂等(deng)鐵(tie)磁(ci)(ci)(ci)性(xing)材(cai)料的(de)被(bei)分為起(qi)重(zhong)電(dian)(dian)(dian)磁(ci)(ci)(ci)鐵(tie)。
