ipali yasentla ichazwa njengepali yemagnethi ethi, xa ikhululekile ukujikeleza, ifune isibonda esisemantla somhlaba.Ngamanye amazwi, isibonda esisemantla semagnethi siya kufuna incam yomhlaba engasentla.Ngokufanayo, isibonda esisemazantsi semagnethi sikhangela ipali esemazantsi yomhlaba.
Iimagnethi zangoku ezisisigxina zenziwe ngeealloyi ezikhethekileyo ezifunyenwe ngophando ukwenza iimagnethi ezingcono.Iintsapho ezixhaphakileyo zezixhobo zemagnethi ezisisigxina namhlanje zenziwe nge-aluminium-nickel-cobalt (alnicos), i-strontium-iron (i-ferrites, eyaziwa ngokuba yi-ceramics), i-neodymium-iron-boron (imagnethi ye-neodymium, okanye "imagnethi ephezulu"). , kunye ne-samarium-cobalt-magnet-material.(Iintsapho ze-samarium-cobalt kunye neodymium-iron-boron zaziwa ngokudibeneyo njengemihlaba enqabileyo).
Gxininisa ekuboneleleni ngezisombululo zemagnethi iminyaka engama-30
