其實人為造出來的人造磁鐵，往往是(shi)被分為(wei)蹄形磁(ci)(ci)(ci)(ci)鐵(tie)和條形磁(ci)(ci)(ci)(ci)鐵(tie)，是(shi)大(da)家生活中常見(jian)的(de)(de)(de)，其中蹄形磁(ci)(ci)(ci)(ci)鐵(tie)比較受(shou)歡迎(ying)。單面(mian)(mian)(mian)(mian)(mian)磁(ci)(ci)(ci)(ci)鐵(tie) 是(shi)指一(yi)(yi)(yi)面(mian)(mian)(mian)(mian)(mian)有(you)(you)磁(ci)(ci)(ci)(ci)性(xing)，另(ling)一(yi)(yi)(yi)面(mian)(mian)(mian)(mian)(mian)磁(ci)(ci)(ci)(ci)性(xing)較弱(ruo)的(de)(de)(de)磁(ci)(ci)(ci)(ci)鐵(tie)，方(fang)法是(shi)用(yong)特別處理的(de)(de)(de)鍍(du)鋅鐵(tie)皮將(jiang)雙(shuang)面(mian)(mian)(mian)(mian)(mian)磁(ci)(ci)(ci)(ci)鐵(tie)的(de)(de)(de)一(yi)(yi)(yi)面(mian)(mian)(mian)(mian)(mian)包裹，這樣(yang)被包裹的(de)(de)(de)一(yi)(yi)(yi)面(mian)(mian)(mian)(mian)(mian)磁(ci)(ci)(ci)(ci)性(xing)將(jiang)被屏(ping)蔽，磁(ci)(ci)(ci)(ci)力被折射到另(ling)一(yi)(yi)(yi)面(mian)(mian)(mian)(mian)(mian)，另(ling)一(yi)(yi)(yi)面(mian)(mian)(mian)(mian)(mian)磁(ci)(ci)(ci)(ci)性(xing)將(jiang)增強。如有(you)(you)的(de)(de)(de)場合只(zhi)需(xu)要(yao)一(yi)(yi)(yi)面(mian)(mian)(mian)(mian)(mian)有(you)(you)磁(ci)(ci)(ci)(ci)性(xing)，另(ling)一(yi)(yi)(yi)面(mian)(mian)(mian)(mian)(mian)如有(you)(you)磁(ci)(ci)(ci)(ci)性(xing)會造成損(sun)壞或干擾(rao)；有(you)(you)的(de)(de)(de)場合如包裝(zhuang)盒上的(de)(de)(de)磁(ci)(ci)(ci)(ci)鐵(tie)則只(zhi)需(xu)要(yao)一(yi)(yi)(yi)面(mian)(mian)(mian)(mian)(mian)有(you)(you)磁(ci)(ci)(ci)(ci)性(xing)，另(ling)一(yi)(yi)(yi)面(mian)(mian)(mian)(mian)(mian)可有(you)(you)可無，有(you)(you)磁(ci)(ci)(ci)(ci)性(xing)也(ye)沒有(you)(you)用(yong)，這樣(yang)使用(yong)單面(mian)(mian)(mian)(mian)(mian)磁(ci)(ci)(ci)(ci)會大(da)大(da)降低成本并(bing)節約磁(ci)(ci)(ci)(ci)性(xing)材料。
