圓管式上海電磁鐵的(de)(de)應(ying)用是(shi)(shi)愈來愈開闊(kuo)，要記牢圓(yuan)(yuan)管式電(dian)(dian)(dian)磁(ci)(ci)(ci)鐵(tie)是(shi)(shi)運用電(dian)(dian)(dian)流的(de)(de)電(dian)(dian)(dian)流磁(ci)(ci)(ci)效應(ying)，使軟鐵(tie)具備(bei)磁(ci)(ci)(ci)性的(de)(de)機器設(she)備(bei)。圓(yuan)(yuan)管式電(dian)(dian)(dian)磁(ci)(ci)(ci)鐵(tie)的(de)(de)線圈姿(zi)勢為(wei)參量，在(zai)工(gong)作(zuo)工(gong)作(zuo)電(dian)(dian)(dian)壓不會(hui)改(gai)變的(de)(de)情況下，線圈的(de)(de)電(dian)(dian)(dian)流也(ye)是(shi)(shi)參量，在(zai)吸(xi)合全過程中不容(rong)易隨磁(ci)(ci)(ci)密(mi)(mi)的(de)(de)改(gai)動(dong)而改(gai)動(dong)。因此，同意實際操作(zuo)頗率過高(gao)，它在(zai)吸(xi)合前磁(ci)(ci)(ci)密(mi)(mi)很大，等效電(dian)(dian)(dian)路的(de)(de)磁(ci)(ci)(ci)電(dian)(dian)(dian)式也(ye)很大，磁(ci)(ci)(ci)通(tong)量小，因此吸(xi)附(fu)力也(ye)較(jiao)小。吸(xi)合后，磁(ci)(ci)(ci)密(mi)(mi)不大，磁(ci)(ci)(ci)電(dian)(dian)(dian)式也(ye)不大，磁(ci)(ci)(ci)通(tong)量更大，電(dian)(dian)(dian)磁(ci)(ci)(ci)感應(ying)吸(xi)附(fu)力也(ye)更大。
