Imashini ya Neodymium(nanone yitwa“NdFeB”, “Neo” cyangwa “NIB” ) ni magnesi zikomeye zihoraho zakozwe na neodymium, fer na boron alloys. Nibice bigize isi idasanzwe ya rukuruzi kandi bifite magnetiki yo hejuru yibintu byose bihoraho. Bitewe nimbaraga zabo za magnetique hamwe nigiciro gito ugereranije, nizo guhitamo kwambere kubakoresha byinshi, ubucuruzi, inganda nubuhanga.
Imashini ya Neodymium ifatwa nkigikomeye kubera magnetisiyasi yuzuye kandi irwanya demagnetisation. Nubwo bihenze kuruta magnetiki ceramic, magnesi zikomeye za neodymium zigira ingaruka zikomeye! Inyungu nyamukuru nuko ushobora gukoresha ubunini butoNdFeB kugirango ugere ku ntego imwe nini nini, ihendutse. Kubera ko ubunini bwibikoresho byose bizagabanuka, birashobora gutuma igabanuka ryibiciro muri rusange.
Niba ibintu bifatika bya magneti ya neodymium bidahindutse kandi ntibigire ingaruka kuri demagnetisation (nkubushyuhe bwo hejuru, umurima wa magneti uhindagurika, imirasire, nibindi), irashobora gutakaza munsi ya 1% yubucucike bwa magneti mumyaka icumi.
Imashini ya Neodymium ntishobora kwibasirwa cyane no guturika no gukonjesha kuruta ibindi bikoresho bidasanzwe bya magneti (nkaSa cobalt (SmCo) ), kandi ikiguzi nacyo kiri hasi. Nyamara, barumva cyane ubushyuhe. Kubikorwa byingenzi, S cobalt irashobora guhitamo neza kuko imiterere ya magnetique ihagaze neza mubushyuhe bwinshi.

N30, N35, N38, N40, N42, N48, N50 na N52 amanota arashobora gukoreshwa kuri magnet ya NdFeB yuburyo bwose. Turabika magnesi muri disiki, inkoni, guhagarika, inkoni nimpeta. Ntabwo magnesi zose za neodymium zigaragara kururu rubuga, niba rero utabonye icyo ukeneye, twandikire.
