Iimveliso zemagnethi zisetyenziswa kakhulu kwiinkalo ezininzi, kubandakanya ishishini, unyango, ubomi basekhaya, unxibelelwano lwe-elektroniki kunye nothutho. Banokuthembeka okuphezulu, i-magnetism ezinzileyo, ukonga amandla, ukukhuselwa kwendalo, ukhuseleko oluhle kunye nokuqina. Baxhasa uhlengahlengiso olwahlukeneyo, nokuba ziimilo zejometri ezilula okanye iimilo ezintsonkothileyo, zinokulungiswa ngokwemfuno, ngaloo ndlela zilungelelanise ngokugqibeleleyo iimeko ezahlukeneyo zesicelo.
