I-N pole kunye ne-S pole yemagnethi zicwangciswe ngokutshintshanayo.Ipali ye-N enye kunye nepali enye zibizwa ngokuba zipere zeepali, kwaye iimotor zinokuba nazo naziphi na iperi yezibonda.Iimagnethi zisetyenziswa kubandakanya i-aluminiyam nickel cobalt umazibuthe osisigxina, iimagnethi ezisisigxina zeferrite kunye neemagnethi ezinqabileyo zomhlaba ezisisigxina (kubandakanya imagnethi esisigxina yesamarium cobalt kunye neodymium iron boron umazibuthe osisigxina).Umkhombandlela wemagneti wahlulwe kwi-parallel magnetization kunye ne-radial magnetization.
