昆山電磁閥生產廠家和大家探(tan)討(tao)一下電磁鐵的原理。

交(jiao)(jiao)流電(dian)(dian)磁(ci)(ci)(ci)鐵(tie)(tie)(tie)在電(dian)(dian)磁(ci)(ci)(ci)感(gan)(gan)應(ying)(ying)線圈插入電(dian)(dian)源后，鐵(tie)(tie)(tie)芯(xin)和電(dian)(dian)樞被磁(ci)(ci)(ci)化，成為極(ji)性(xing)相(xiang)反的(de)(de)兩塊磁(ci)(ci)(ci)石，在其(qi)中(zhong)間產生電(dian)(dian)磁(ci)(ci)(ci)感(gan)(gan)應(ying)(ying)吸(xi)引力(li)。當吸(xi)力(li)超過彈黃(huang)的(de)(de)反作用(yong)(yong)(yong)力(li)時，銜鐵(tie)(tie)(tie)逐漸朝著鐵(tie)(tie)(tie)芯(xin)方位健(jian)身運動。當線圈中(zhong)的(de)(de)電(dian)(dian)流量低于(yu)某(mou)一定(ding)值(zhi)或終斷供電(dian)(dian)系統時，黃(huang)銅電(dian)(dian)磁(ci)(ci)(ci)閥電(dian)(dian)磁(ci)(ci)(ci)感(gan)(gan)應(ying)(ying)吸(xi)力(li)低于(yu)彈黃(huang)的(de)(de)反作用(yong)(yong)(yong)力(li)，銜鐵(tie)(tie)(tie)將(jiang)在反作用(yong)(yong)(yong)力(li)的(de)(de)功效下回到原先的(de)(de)釋放出來部位。交(jiao)(jiao)流電(dian)(dian)磁(ci)(ci)(ci)鐵(tie)(tie)(tie)是一種利用(yong)(yong)(yong)載流鐵(tie)(tie)(tie)芯(xin)引起的(de)(de)電(dian)(dian)磁(ci)(ci)(ci)感(gan)(gan)應(ying)(ying)吸(xi)力(li)，用(yong)(yong)(yong)來控制機械設備、使其(qi)保持預定(ding)姿態的(de)(de)家電(dian)(dian)。它是將(jiang)電(dian)(dian)磁(ci)(ci)(ci)能(neng)(neng)變(bian)換為機械動能(neng)(neng)的(de)(de)一種二通電(dian)(dian)磁(ci)(ci)(ci)閥電(dian)(dian)磁(ci)(ci)(ci)感(gan)(gan)應(ying)(ying)元(yuan)器件。

溝通交流電磁鐵的常見問題：

(1)將軟鐵棒插入螺旋線圈內部時，線圈通電后，線圈內部的電磁場將軟鐵棒磁化為臨時磁石，但電流量斷開時，線圈和軟鐵棒的磁帶消失。

(2)軟鐵棒被磁化后所轉化成的電磁場，再加上原來線圈內的電磁場，促使總磁化強度大幅提高，故電磁鐵的磁性超過純天然磁石。

(3)螺旋線圈的電流越大，線圈匝數越多，電磁場越強。
