Imagnethi yokuhlangula yimagnethi enamandla eyenzelwe ukusetyenziswa kwizicelo ezahlukeneyo ezifuna ukuphakamisa kunye nokubuyisela izinto zentsimbi enzima emanzini okanye kwezinye iindawo ezinomngeni. Ezi magnethi zenziwe ngezixhobo zodidi oluphezulu, ezinjenge-neodymium okanye i-ceramic, kwaye zinokuvelisa indawo eyomeleleyo kazibuthe ekwaziyo ukuphakamisa imithwalo enzima.
Iimagnethi zokuhlangula zidla ngokusetyenziswa kwizicelo ezinje ngokuhlangula, uphononongo lwangaphantsi kwamanzi, kunye noseto lwemizi-mveliso apho ububutyobo besinyithi kufuneka buqokelelwe okanye buthathwe. Zikwasetyenziswa ekulobeni ukukhupha amagwegwe alahlekileyo, izinto zokutsala, nezinye izinto zentsimbi emanzini.
