(ekwabizwa ngokuba yiCup magnets, Mounting magnets) zibandakanya oomazibuthe abavalelwe kwikomityi yentsimbi, umazibuthe wangaphakathi unokuba neodymium, smco, alnico okanye ferrite, ungakhetha eyona imathiriyeli ifanelekileyo ngokwendawo eya kusetyenziswa kuyo.Amandla omagnetic wemagnethi yembiza yomelele kakhulu, ke ngoko asetyenziswa ngokubanzi kwimisebenzi yokuphatha enzima, ikhuselekile ngenxa yokuba inomagnethi ngokusisigxina, uthotho olupheleleyo oluneendlela ezahlukeneyo zokulungisa kunye nobukhulu buyafumaneka, ungayifumana ngokulula indlela. ukuzilungisa, ngenxa yolu ncedo, kwandisa kakhulu usetyenziso lweemagnethi zembiza kurhwebo nakwimizi-mveliso, njengegumbi lokusebenzela, iofisi, ivenkile kunye nekhaya.
