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.
