框架上海電(dian)磁鐵的(de)介紹(shao)
框架式上(shang)(shang)(shang)海(hai)(hai)電(dian)(dian)磁(ci)(ci)鐵(tie)又稱箱式上(shang)(shang)(shang)海(hai)(hai)電(dian)(dian)磁(ci)(ci)鐵(tie)，因為(wei)它(ta)的(de)形(xing)狀(zhuang)是方形(xing)的(de)。這(zhe)種框架上(shang)(shang)(shang)海(hai)(hai)電(dian)(dian)磁(ci)(ci)鐵(tie)是一種產生電(dian)(dian)磁(ci)(ci)的(de)設備。當變壓器(qi)鐵(tie)心在(zai)外旋轉，其輸(shu)出功率(lv)與導電(dian)(dian)繞組電(dian)(dian)阻一致時(shi)(shi)，帶電(dian)(dian)流的(de)線圈具(ju)有(you)與磁(ci)(ci)鐵(tie)相同(tong)的(de)磁(ci)(ci)性。我(wo)們(men)通常(chang)(chang)把它(ta)做成條狀(zhuang)或(huo)蹄狀(zhuang)，使它(ta)的(de)變壓器(qi)鐵(tie)心更容易磁(ci)(ci)化。另外，為(wei)了使上(shang)(shang)(shang)海(hai)(hai)電(dian)(dian)磁(ci)(ci)鐵(tie)立即(ji)斷電(dian)(dian)消(xiao)(xiao)磁(ci)(ci)，我(wo)們(men)經常(chang)(chang)采用快速(su)消(xiao)(xiao)磁(ci)(ci)的(de)軟鐵(tie)或(huo)硅鋼材料制作。這(zhe)種上(shang)(shang)(shang)海(hai)(hai)電(dian)(dian)磁(ci)(ci)鐵(tie)插上(shang)(shang)(shang)電(dian)(dian)源就(jiu)會有(you)磁(ci)(ci)性。當電(dian)(dian)源關閉時(shi)(shi)，磁(ci)(ci)場將消(xiao)(xiao)失(shi)。方形(xing)上(shang)(shang)(shang)海(hai)(hai)電(dian)(dian)磁(ci)(ci)鐵(tie)在(zai)我(wo)們(men)的(de)日(ri)常(chang)(chang)生活中(zhong)有(you)很(hen)多用途，
