Ibikoresho bya magneti birashobora gushyirwa mubyiciro bibiri: magnet isotropic na magnet anisotropic:
Imashini ya Isotropique yerekana ibintu bimwe bya magneti muburyo bwose kandi irashobora gukwega icyerekezo icyo aricyo cyose.
Imashini ya Anisotropique yerekana ibintu bitandukanye bya magnetiki mubyerekezo bitandukanye, kandi bifite icyerekezo cyiza kubikorwa bya magnetiki byiza, bizwi nkicyerekezo cyerekezo.
Imashini isanzwe ya anisotropique irimoIcyaha NdFeBnaIcyaha SmCo, byombi nibikoresho bikomeye bya magneti.
Icyerekezo ninzira yingenzi mugukora magnet ya NdFeB yacumuye
Magnetisme ya rukuruzi ikomoka kumurongo wa magneti (aho magnetiki ya domaine yihariye ihuza icyerekezo runaka).NdFeB yacumuye ikorwa mugukanda ifu ya magneti mubibumbano.Inzira ikubiyemo gushyira ifu ya magneti mubibumbano, gukoresha umurima ukomeye wa magneti ukoresheje electromagnet, kandi icyarimwe ugashyiraho igitutu hamwe na kanda kugirango uhuze umurongo woroshye wa magnetisiyasi yifu.Nyuma yo gukanda, imibiri yicyatsi iba demagnetisme, ikurwa mubibumbano, hanyuma ibisubizo bivamo hamwe na magnetisiyoneri yerekanwe neza.Ibyo bisobanuro noneho bigabanywa mubipimo byihariye kugirango habeho ibicuruzwa bya magnetiki byanyuma ukurikije ibyo abakiriya bakeneye.
Icyerekezo cya Powder ninzira yingenzi mugukora cyane-NdFeB ikora magnesi zihoraho.Ubwiza bwicyerekezo mugihe cyumusaruro wubusa buterwa nibintu bitandukanye, harimo imbaraga zicyerekezo cyumurima, ifu yifu yubunini nubunini, uburyo bwo gukora, icyerekezo ugereranije cyerekezo cyumurima hamwe nigitutu, hamwe nubucucike bwifu yifu.
Magnetic skew yakozwe mubyiciro nyuma yo gutunganyirizwa igira ingaruka runaka kumasoko ya magneti ikwirakwizwa rya magnesi.
Magnetisation nintambwe yanyuma yo gutanga magnetism kuriIcyaha NdFeB.
Nyuma yo guca magnetiki yubusa kubipimo byifuzwa, bahura nibikorwa nka electroplating kugirango birinde kwangirika no guhinduka magneti ya nyuma.Nyamara, kuri iki cyiciro, magnesi ntagaragaza magnetisme yo hanze kandi bisaba magnetisiyasi binyuze mubikorwa bizwi nka "kwishyuza magnetism."
Ibikoresho bikoreshwa mugukoresha magnetisiti bita magnetizer, cyangwa imashini ya magnetizing.Magnetizer yabanje kwishyiriraho capacitor ifite ingufu za DC nyinshi (ni ukuvuga kubika ingufu), hanyuma ikayirekura ikoresheje coil (magnetizing fixture) ifite imbaraga nke cyane.Impinga yumuvuduko wimpanuka irashobora kuba ndende cyane, igera ku bihumbi mirongo amperes.Iyi pulse yubu itanga imbaraga zikomeye za magnetique murwego rwa rukuruzi, rukuruzi ya magneti ihoraho imbere.
Impanuka zirashobora kubaho mugihe cya magnetisiyonike, nko kwiyuzuzamo kutuzuye, kumenagura inkingi za magneti, no kuvunika kwa magneti.
Kwiyuzura kutuzuye guterwa ahanini na voltage yumuriro idahagije, aho umurima wa magneti ukorwa na coil utagera inshuro 1.5 kugeza kuri 2 zuzuye za rukuruzi.
Kuri magnetisiyonike, magnesi hamwe nicyerekezo cyerekezo cyerekezo nazo ziragoye kuzura byuzuye.Ibi ni ukubera ko intera iri hagati yinkingi yo hejuru nu hepfo ya magnetizer ari nini cyane, bigatuma imbaraga za magnetique zidahagije ziva mumigozi kugirango zibe uruziga rukwiye.Nkigisubizo, inzira ya magnetisiyasiyo irashobora kuganisha kumurongo wa magneti udahungabana hamwe nimbaraga zidahagije zumurima.
Kumenagura inkingi ya magnetizer biterwa cyane cyane no gushiraho voltage hejuru cyane, ikarenga imipaka yumutekano itekanye ya mashini.
Imashini zidahagije cyangwa magnesi zagiye zigabanywa igice biragoye kuzura bitewe nububiko bwazo bwa magneti.Kugirango ugere ku kwiyuzuzamo, kurwanya kuva kwimurwa no kuzunguruka kuri domaine bigomba kuneshwa.Ariko, mugihe aho rukuruzi ituzuye cyangwa ifite magnetisiyasi isigaye, hari uturere twumwanya wa magnetiki imbere.Haba magnetisite mu cyerekezo cyerekeza cyangwa cyinyuma, uduce tumwe na tumwe dusaba guhinduranya imbaraga, bisaba gutsinda imbaraga zagahato zinjira muri utwo turere.Kubwibyo, imbaraga za magneti zikomeye kuruta izikenewe zirakenewe kugirango rukuruzi.
