Iimagnethi ezisisigxina zomhlaba, ngakumbi ezo zenziwe ngezinto ezifana neodymium, samarium-cobalt, kunye nezinye, zidlala indima ebalulekileyo koomatshini bonyango kunye nezixhobo ezisetyenziswa ezibhedlele. Iipropathi zabo ezizodwa, ezinje ngamandla kamagnethi aphezulu kunye nokuchasana ne-demagnetization, zibenza balungele izicelo ezininzi ezibalulekileyo.
