Ubushobozi bwa rukuruzi ihoraho yo gushyigikira umurima wa magneti wo hanze biterwa na anisotropiya ya kirisiti mu bikoresho bya rukuruzi "ifunga" domaine ntoya ya magneti.Iyo magnetisiyasi yambere imaze gushingwa, iyi myanya ikomeza kuba imwe kugeza igihe imbaraga zirenze imbaraga za magneti zifunze zikoreshwa, kandi imbaraga zisabwa kugirango zibangamire umurima wa rukuruzi zakozwe na rukuruzi zihoraho ziratandukanye kuri buri kintu.Imashini zihoraho zishobora kubyara imbaraga nyinshi cyane (Hcj), zigakomeza guhuza indangarugero imbere yumurima mwinshi wo hanze.

Ihungabana rishobora gusobanurwa nkibintu bisubirwamo bya magnetiki yibintu mubihe byagenwe hejuru yubuzima bwa rukuruzi.Ibintu bigira ingaruka kumyuka ya magneti harimo igihe, ubushyuhe, impinduka mubushake, imirima mibi ya magneti, imirasire, ihungabana, guhangayika, no kunyeganyega.

Igihe ntigifite ingaruka nke kuri magnesi zihoraho, ubushakashatsi bwerekanye impinduka ako kanya nyuma ya magnetisation.Izi mpinduka, zizwi nka "magnetiki creep," zibaho mugihe imbaraga zidasanzwe za magneti zidafite ingaruka ziterwa nihindagurika ryingufu zumuriro cyangwa magnetique, ndetse no mubidukikije bihamye.Iri tandukaniro rigabanuka uko umubare w’uturere udahungabana ugabanuka.

Ntibisanzwe isi ya magneti ntishobora guhura niyi ngaruka kubera guhatira cyane.Ubushakashatsi bugereranije bwigihe kirekire na magnetiki flux yerekana ko magneti mashya ya magneti ahoraho atakaza urugero ruke rwa magneti mugihe runaka.Mugihe cyamasaha arenga 100.000, gutakaza ibikoresho bya samarium cobalt mubusanzwe ni zeru, mugihe gutakaza ibikoresho byoroheje bya Alnico bitarenze 3%.

Ingaruka z'ubushyuhe ziri mu byiciro bitatu: igihombo kidasubirwaho, igihombo kidasubirwaho ariko gishobora kugarurwa, hamwe nigihombo kidasubirwaho kandi kidasubirwaho.

Igihombo gisubira inyuma: Izi nigihombo gisubirana iyo rukuruzi igarutse mubushyuhe bwayo bwambere, ihinduka rya magneti rihoraho ntirishobora gukuraho igihombo gisubira inyuma.Igihombo gisubira inyuma gisobanurwa nubushyuhe bwo guhinduka (Tc), nkuko bigaragara mumbonerahamwe ikurikira.Tc igaragazwa nkijanisha kuri dogere selisiyusi, iyi mibare iratandukanye nicyiciro cyihariye cya buri kintu, ariko gihagarariye icyiciro cyibintu muri rusange.Ni ukubera ko coefficient ya Br na Hcj itandukanye cyane, bityo umurongo wa demagnetisation uzagira "inflection point" mubushyuhe bwinshi.

Igihombo kidasubirwaho ariko gishobora kugarurwa: Ibi bihombo bisobanurwa nkigice cya demagnetisation igice cya magneti kubera guhura nubushyuhe bwo hejuru cyangwa buke, ibyo bihombo birashobora kugarurwa gusa na re-magnetisation, magnetism ntishobora gukira mugihe ubushyuhe bwasubiye mubyagaciro byambere.Ibi bihombo bibaho mugihe aho imikorere ya magneti iri munsi yumwanya wa demagnetisation.Igishushanyo mbonera gihoraho kigomba kugira umuzenguruko wa rukuruzi aho rukuruzi ikorera hamwe nubucucike burenze aho ihindagurika ryumurongo wa demagnetisiyonike ku bushyuhe bwo hejuru buteganijwe, bizarinda ihinduka ryimikorere mubushyuhe bwinshi.

Igihombo kidasubirwaho Igihombo: Magneti ihura nubushyuhe bwo hejuru cyane ihindura metallurgjique idashobora kugarurwa na remagnetisation.Imbonerahamwe ikurikira irerekana ubushyuhe bukomeye bwibikoresho bitandukanye, aho: Tcurie nubushyuhe bwa Curie aho umwanya wa magnetiki wibanze uteganijwe kandi ibikoresho bigasuzumwa;Tmax nubushyuhe ntarengwa bwo gukora bwibikoresho byibanze murwego rusange.

Imashini zikora ubushyuhe butajegajega igice cya magnesi mu kwerekana ubushyuhe bwinshi muburyo bugenzurwa.Kugabanuka gake mubucucike bwa flux bitezimbere ituze rya magneti, kubera ko domaine nkeya zidafite icyerekezo cyambere cyo gutakaza icyerekezo.Imashini zihamye zizagaragaza imbaraga za magneti zihoraho mugihe zihuye nubushyuhe buke cyangwa buke.Byongeye kandi, icyiciro gihamye cya magnesi kizagaragaza itandukaniro rito mugihe ugereranije nundi, kubera ko hejuru yumurongo w inzogera hamwe nibisanzwe bitandukana bizaba byegeranye nagaciro keza.
