Maginito ang'onoang'ono a neodymium cube ndi mtundu wamaginito amphamvu a neodymiumzomwe nthawi zambiri zimagwiritsidwa ntchito pazinthu zosiyanasiyana monga ma motors amagetsi, masensa, ndi makina a maginito a resonance imaging (MRI). Maginitowa amapangidwa kuchokera ku aloyi ya neodymium, chitsulo, ndi boron, zomwe zimapatsa mphamvu zawo maginito.Maginito ang'onoang'ono a cube a neodymium amapezeka mumitundu yosiyanasiyana, kuyambira mamilimita angapo mpaka ma centimita angapo muutali.
Nthawi zambiri amagwiritsidwa ntchito ngati maginito ophatikizana, amphamvu amafunikira, monga zamagetsi kapena kuyika zinthu m'malo mwake.Ndikofunikira kugwira maginito a neodymium mosamala chifukwa ndi amphamvu kwambiri ndipo amatha kuvulaza ngati sanagwire bwino. Ziyenera kusungidwa kutali ndi ana ndi ziweto, ndipo zisamezedwe kapena kuziyika pafupi ndi zipangizo zamagetsi, makina othamanga, kapena zipangizo zina zachipatala. Kuphatikiza apo, maginito a neodymium amayenera kusungidwa kutali ndi maginito ena kapena zida zamaginito kuti apewe demagnetization. Ngati muli ndi ndondomeko yogulamtengo wa neodymium maginito kyubukuchokera ku China, mutha kulumikizana ndi Fullzen Factory yemwe ndi isasquare maginito fakitale. Ngati mukufunazambiri neodymium maginito kyubu, tidzakuthandizani kuthana ndi mavuto anu.
Maginito okhazikika ndi maginito omwe amakhalabe ndi maginito pambuyo pokhala ndi maginito. Maginito osatha amapangidwa kuchokera ku zinthu monga chitsulo, cobalt, ndi faifi tambala, komanso zinthu zomwe sizipezeka padziko lapansi monga neodymium ndi samarium-cobalt.
Mphamvu ya maginito ya maginito okhazikika imapangidwa ndi kulumikizana kwa maginito a ma atomu mkati mwa zinthuzo. Maginitowa akamalumikizana, amapanga mphamvu ya maginito yomwe imadutsa pamwamba pa maginito. Mphamvu ya maginito imadalira mphamvu ya nthawi ya maginito ndi kuyanjanitsa kwa ma atomu mkati mwa zinthuzo.
Maginito osatha amagwiritsidwa ntchito m'njira zosiyanasiyana monga ma mota amagetsi, ma jenereta, ndi zida zosungira maginito. Amagwiritsidwanso ntchito pazinthu zatsiku ndi tsiku monga maginito a firiji ndi zoseweretsa zamaginito.
Mphamvu ya maginito okhazikika imayesedwa mu mayunitsi a maginito kachulukidwe ka maginito, kapena tesla (T), ndipo imatsimikiziridwa ndi zida zomwe zimagwiritsidwa ntchito komanso momwe amapangira. Mphamvu ya maginito a neodymium, mwachitsanzo, imatha kuchoka pa ma gauss mazana angapo mpaka kupitilira 1.4 tesla.
Kutumiza Kwachangu Padziko Lonse:Kumanani ndi kunyamula kotetezedwa kwa mpweya ndi nyanja, Kupitilira zaka 10 zakutumiza kunja
Zosinthidwa Mwamakonda Zilipo:Chonde perekani chojambula cha mapangidwe anu apadera
Mtengo Wotsika:Kusankha zinthu zabwino kwambiri kumatanthauza kupulumutsa ndalama.
Izi neodymium maginito chimbale ali awiri a 50mm ndi kutalika kwa 25mm. Ili ndi maginito owerengera a 4664 Gauss ndi mphamvu yokoka ya 68.22 kilos.
Maginito amphamvu, monga disiki ya Rare Earth iyi, amapangira mphamvu ya maginito yomwe imatha kulowa muzinthu zolimba monga matabwa, galasi kapena pulasitiki. Kutha kumeneku kumagwira ntchito kwa amalonda ndi mainjiniya komwe maginito amphamvu angagwiritsidwe ntchito kuzindikira zitsulo kapena kukhala zida zama alamu ndi loko zotetezedwa.
Kalasi ya maginito a neodymium, monga N35, N40, N42, N45, N48, N50, kapena N52, imatanthawuza mphamvu yake yamaginito ndi mawonekedwe ake. Magirediwa ndi njira yokhazikika yowonetsera mphamvu ya maginito, yomwe ndi muyeso wa kuchuluka kwake kwa mphamvu yamaginito. Nambala yapamwamba imawonetsa maginito amphamvu. Mwachitsanzo, maginito a N52 ndi amphamvu kuposa maginito a N35.
Mphamvu ya maginito ya neodymium imayesedwa mu MegaGauss Oersteds (MGOe) kapena Joules pa kiyubiki mita (J/m³). Kukwera mtengo, mphamvu ya maginito yomwe maginito imatha kupanga. Ndikofunika kuzindikira kuti maginito apamwamba kwambiri nthawi zambiri amatha kutenthedwa ndi kutentha ndi demagnetization zotsatira.
Kudula, kubowola, kapena kupanga maginito a neodymium ndikotheka, koma pamafunika zida zapadera, ukatswiri, ndi kusamala chifukwa cha kulimba kwa maginito komanso kuthekera kusweka kapena kusweka. Ngati sizichitika mosamalitsa, njirazi zimatha kuwononga maginito, kuwononga maginito, kapena kuvulaza.
Kuwotcherera kapena kuwotcherera maginito a neodymium nthawi zambiri sikuvomerezeka chifukwa cha chidwi chawo chachikulu pakutentha. Maginito a Neodymium amapangidwa kuchokera kuzinthu zomwe zimatha kutaya maginito kapena kuwonongeka zikakumana ndi kutentha kwambiri. Kuwotcherera kapena kuwotcherera kungapangitse kutentha komwe kungakhudze magwiridwe antchito ndi kukhulupirika kwa maginito.
Inde, muyenera kusamala za kutentha mukamagwira ntchito ndi maginito a neodymium. Maginito a Neodymium amakhudzidwa ndi kusintha kwa kutentha, ndipo kukhudzana ndi kutentha kwapamwamba kumatha kukhudza maginito awo. Nazi zomwe muyenera kudziwa:
Kutentha kwa Curie: Maginito a Neodymium ali ndi kutentha koopsa kotchedwa Curie kutentha (Tc), komwe ndi kutentha komwe amayamba kutaya mphamvu zawo zamaginito. Kwa maginito ambiri a neodymium, kutentha kwa Curie kumakhala pakati pa 80°C ndi 200°C, kutengera giredi ndi kapangidwe kake.
Fullzen Magnetics ali ndi zaka zopitilira 10 pakupanga ndi kupanga maginito osowa padziko lapansi. Titumizireni pempho la mtengo wamtengo wapatali kapena mutitumizireni lero kuti tikambirane zofunikira za polojekiti yanu, ndipo gulu lathu la mainjiniya odziwa zambiri likuthandizani kudziwa njira yotsika mtengo kwambiri yokupatsirani zomwe mukufuna.Titumizireni tsatanetsatane wanu wokhudza momwe maginito amagwirira ntchito.
