牽(qian)引電磁鐵可(ke)以(yi)被(bei)理解(jie)為主要用來牽(qian)引機械裝置、開(kai)啟(qi)或者關閉各種閥門，以(yi)執行自(zi)動控制(zhi)任(ren)務。

常(chang)見(jian)的牽引電(dian)磁(ci)鐵的鐵芯都是(shi)軟磁(ci)性材料而制(zhi)，它的作用顯而易(yi)見(jian)，如對(dui)電(dian)動機(ji)進行制(zhi)動以達到準確(que)停車的目的叫(jiao)制(zhi)動電(dian)磁(ci)鐵;

電(dian)(dian)磁(ci)(ci)繼電(dian)(dian)器(qi)(qi)和接觸器(qi)(qi)的電(dian)(dian)磁(ci)(ci)系(xi)統(tong)(tong)、自動開(kai)關的電(dian)(dian)磁(ci)(ci)脫扣器(qi)(qi)及操作(zuo)的被(bei)稱為自動電(dian)(dian)器(qi)(qi)電(dian)(dian)磁(ci)(ci)控(kong)制系(xi)統(tong)(tong)電(dian)(dian)磁(ci)(ci)鐵(tie)，還有一類用于起(qi)重(zhong)裝(zhuang)置來吊運鋼錠、鋼材、鐵(tie)砂(sha)等鐵(tie)磁(ci)(ci)性(xing)材料的被(bei)分為起(qi)重(zhong)電(dian)(dian)磁(ci)(ci)鐵(tie)。
