Lapho amandla ashintshayo afakwa emsindweni, uzibuthe uba yizibuthe kagesi.Indlela yamanje ishintsha njalo, futhi i-electromagnetic ilokhu ihamba iya emuva naphambili ngenxa "yokunyakaza kwamandla kocingo olunamandla endaweni kazibuthe", ukushayela umcengezi wephepha ukudlidliza emuva naphambili.Isitiriyo sinomsindo.
Ozibuthe ophondweni ikakhulukazi bahlanganisa uzibuthe we-ferrite kanye nozibuthe we-NdFeB.Ngokusho kwesicelo, odonsa be-NdFeB basetshenziswa kakhulu emikhiqizweni ye-elekthronikhi, njengama-hard disk, omakhalekhukhwini, ama-headphone namathuluzi asebenza ngebhethri.Umsindo mkhulu.
