Iyo impinduka ihindagurika igaburiwe mumajwi, magnet iba electronique. Icyerekezo kigezweho gihinduka buri gihe, kandi electromagnet ikomeza kugenda isubira inyuma bitewe n "imbaraga zigenda zinsinga zingufu mumashanyarazi", bigatuma ikibase cyimpapuro kinyeganyeza inyuma. Stereo ifite amajwi.
Imashini zihembe zirimo magnite ferrite na magnet ya NdFeB. Ukurikije porogaramu, magnet ya NdFeB ikoreshwa cyane mubicuruzwa bya elegitoronike, nka disiki zikomeye, terefone zigendanwa, na terefone n'ibikoresho bikoresha ingufu za batiri. Ijwi riranguruye.
