Zipangizo zamaginito zitha kugawidwa m'magulu awiri: maginito a isotropic ndi maginito a anisotropic:
Maginito a isotropic amawonetsa maginito omwewo mbali zonse ndipo amatha kukhala ndi maginito mbali iliyonse.
Maginito a Anisotropic amawonetsa maginito osiyanasiyana mbali zosiyanasiyana, ndipo amakhala ndi njira yomwe amakonda kuti agwire bwino ntchito, yomwe imadziwika kuti njira yolowera.
Maginito wamba anisotropic akuphatikizaposinter NdFeBndisintered SmCo, zomwe zonse ndi zolimba maginito.
Kuwongolera ndi njira yofunika kwambiri popanga maginito a sintered NdFeB
Mphamvu ya maginito ya maginito imachokera ku dongosolo la maginito (kumene madera a maginito amalumikizana mbali ina yake).Sintered NdFeB amapangidwa ndi compressing maginito ufa mkati zisamere pachakudya.Njirayi imaphatikizapo kuyika ufa wa maginito mu nkhungu, kugwiritsa ntchito mphamvu ya maginito pogwiritsa ntchito electromagnet, ndi nthawi yomweyo kukakamiza ndi makina osindikizira kuti agwirizane ndi njira yosavuta ya magnetization ya ufa.Pambuyo kukanikiza, matupi obiriwira amachotsedwa maginito, amachotsedwa mu nkhungu, ndipo zomwe zimasokonekera zokhala ndi malangizo olowera bwino a maginito amapezedwa.Zosowa izi zimadulidwa mumiyeso yodziwika kuti apange zitsulo zomaliza zamaginito malinga ndi zomwe makasitomala amafuna.
Kuwongolera ufa ndi njira yofunika kwambiri popanga maginito okhazikika a NdFeB.Ubwino wa zochitika pa gawo lopanda kanthu lopanga zinthu umakhudzidwa ndi zinthu zosiyanasiyana, kuphatikiza mphamvu yakumunda, mawonekedwe a tinthu tating'ono ndi kukula kwake, njira yopangira, mawonekedwe achibale a gawo loyang'anira ndikupanga kukakamiza, komanso kusalimba kwa ufa wokhazikika.
Maginito skew opangidwa mu post-processing siteji ali ndi mphamvu pa maginito kugawa maginito.
Magnetization ndiye gawo lomaliza lopereka maginito kusinter NdFeB.
Atatha kudula maginito omwe akusowekapo pamiyeso yomwe akufuna, amakumana ndi njira monga electroplating kuti ateteze dzimbiri ndikukhala maginito omaliza.Komabe, panthawiyi, maginito samawonetsa maginito akunja ndipo amafuna magnetization kudzera mu njira yotchedwa "charging magnetism."
Zipangizo zomwe zimagwiritsidwa ntchito popanga maginito zimatchedwa magnetizer, kapena makina opangira maginito.Magnetizer imayamba kuyitanitsa capacitor yokhala ndi voliyumu yayikulu ya DC (ie, imasunga mphamvu), kenako imayitulutsa kudzera pa koyilo (yopangidwa ndi magnetizing) yokhala ndi kukana kochepa kwambiri.Kuthamanga kwapamwamba kwa pulse yotulutsa kumatha kukhala kokwera kwambiri, kufika makumi masauzande a amperes.Kugunda kwapano kumeneku kumapanga mphamvu ya maginito mkati mwa magnetizing fixture, yomwe imapangitsa maginito maginito omwe ayikidwa mkati.
Ngozi zimatha kuchitika panthawi ya maginito, monga kusakwanira bwino, kusweka kwa mitengo ya maginito, ndi kusweka kwa maginito.
Machulukitsidwe chosakwanira makamaka chifukwa chosakwanira naza voteji, kumene maginito kwaiye ndi koyilo si kufika 1.5 mpaka 2 nthawi machulukitsidwe maginito maginito.
Pa multipole magnetization, maginito okhala ndi mayendedwe otalikirapo amakhalanso ovuta kuti akhute mokwanira.Izi zili choncho chifukwa mtunda wapakati pa mitengo ya kumtunda ndi yapansi ya maginito ndi yaikulu kwambiri, zomwe zimapangitsa kuti maginito asakhale ndi mphamvu zokwanira kuchokera kumitengo kuti apange dera lotsekedwa lotsekedwa la maginito.Zotsatira zake, njira ya maginito imatha kubweretsa mizati yosagwirizana ndi maginito komanso mphamvu zamunda zosakwanira.
Kuthyoka kwa mitengo ya maginito kumayamba chifukwa chokhazikitsa voteji yokwera kwambiri, kupitilira malire otetezeka amagetsi a makina opangira maginito.
Maginito opanda unsaturated kapena maginito omwe alibe maginito pang'ono ndi ovuta kudzaza chifukwa cha madera awo oyambirira osokonezeka.Kuti mukwaniritse machulukitsidwe, kukana kusuntha ndi kuzungulira kwa madambwe awa kuyenera kugonjetsedwa.Komabe, ngati maginito sakhuta kapena kukhala ndi maginito otsalira, pamakhala madera a reverse magnetic field mkati mwake.Kaya magnetizing kutsogolo kapena m'mbuyo mbali, madera ena amafuna reverse magnetization, kutanthauza kugonjetsa mwachibadwa mphamvu mphamvu m'madera amenewa.Choncho, mphamvu maginito mphamvu kuposa theoretically chofunika n'kofunika kuti maginito.
