Iimagnethi zePot zikwabizwa ngokuba ziiMaginethi eziSiseko esiRound okanye iimagnethi zeNdebe yeRound, iimagnethi zeRB, iimagnethi zekomityi, ziindibano zekomityi zemagnethi ezibandakanya i-neodymium okanye iimagnethi zeringi ezibiyelwe kwikomityi yentsimbi ene-countersunk okanye umngxuma obambeneyo wokuxhoma. Ngolu hlobo loyilo, amandla okubamba imagnethi kwezi ndibano zemagnethi aphindaphindwa kaninzi kwaye womelele kakhulu kunemagnethi nganye.
Iimagnethi zembiza ziimagnethi ezikhethekileyo, ingakumbi ezo zinkulu, zisetyenziswa kwishishini njengemagnethi yeshishini. Undoqo wemagnethi wemagnethi yembiza yenziwe nge-neodymium kwaye itshonelwa kwimbiza yentsimbi ukuze kuqiniswe amandla okuncamathelisa umazibuthe. Yiyo loo nto zibizwa ngokuba ziimagnethi "zembiza".
