1.Kodi maginito a neodymium ndi neodymium yoyera?
Pali mayina ambiri omwe timatcha maginito a neodymium, koma amatha kutchedwanso maginito a NdFeB, maginito a NEO kapena mayina ena. Pogwiritsa ntchito mayinawa, tikudziwa kuti maginito a neodymium ali ndi zinthu zosiyanasiyana zachitsulo, osachepera tikhoza kukhala otsimikiza kuti maginito a neodymium ali ndi neodymium, chitsulo ndi boron.
Maginito a Neodymium amapangidwa pophatikiza neodymium, chitsulo, ndi boron palimodzi kuti apange maginito okhazikika omwe amadziwika kuti neodymium-iron-boron (NdFeB) maginito. Neodymium mu maginito amenewa nthawi zambiri si oyera, koma aloyi wopangidwa ndi neodymium ndi zinthu zina monga dysprosium, terbium, kapena praseodymium.
Kuwonjezera zinthu zina zimenezi neodymium kumathandiza kusintha maginito katundu NdFeB maginito, monga kuwonjezera coercivity awo ndi kukana demagnetization. Kapangidwe kake ka aloyi a neodymium omwe amagwiritsidwa ntchito mu maginito a NdFeB amatha kusiyanasiyana kutengera momwe amagwiritsira ntchito komanso zofunikira.

2.Kodi maginito a neodymium ndi chiyani?
Maginito a Neodymium ndi mtundu wa maginito amphamvu, okhazikika opangidwa kuchokera ku aloyi ya neodymium, chitsulo, ndi boron. Amadziwikanso kuti neodymium-iron-boron (NdFeB) maginito kapena maginito osowa padziko lapansi, popeza neodymium ndi imodzi mwazinthu zosowa padziko lapansi.
Maginito a Neodymium ndi amphamvu kwambiri, okhala ndi maginito omwe ndi amphamvu kwambiri kuposa maginito amtundu wina, monga maginito a ferrite kapena alnico. Amakhala ndi ntchito zosiyanasiyana, kuphatikiza kugwiritsa ntchito pa hard drive ya pakompyuta, makina opangira mphepo, ma mota amagetsi, zida zamankhwala, ndi zomvetsera.
Chifukwa cha mphamvu zawo, maginito a neodymium amatha kugwiritsidwa ntchito pang'onopang'ono ndipo amaperekabe mphamvu ya maginito. Nthawi zambiri amagwiritsidwa ntchito pazida zamagetsi zamagetsi zomwe malo amakhala ochepa. Komabe, maginito a neodymium nawonso ndi olimba kwambiri ndipo amatha kusweka kapena kusweka mosavuta, motero amayenera kugwiridwa mosamala.
Ponseponse, maginito a neodymium ndi gawo lofunikira kwambiri pamakina amakono ambiri chifukwa champhamvu zawo zamaginito komanso kusinthasintha.
3.Kodi moyo wa maginito a neodymium ndi wotani?
Maginito a Neodymium amadziwika ndi mphamvu ya maginito, koma amakhala ndi moyo wautali. Moyo wa maginito a neodymium ukhoza kusiyana malinga ndi zinthu zingapo, kuphatikizapo kukula kwake, mawonekedwe ake, ndi malo omwe amagwiritsidwa ntchito.
Nthawi zambiri, maginito a neodymium ndi olimba kwambiri ndipo amatha zaka zambiri, ngakhale makumi angapo, ngati atagwiritsidwa ntchito ndikusamalidwa bwino. Komabe, amathanso kutaya mphamvu zawo zamaginito pakapita nthawi, makamaka ngati akumana ndi kutentha kwambiri kapena maginito amphamvu.
Kutalika kwenikweni kwa maginito a neodymium kungakhale kovuta kuneneratu, chifukwa zimatengera zinthu zambiri. Koma ndi chisamaliro choyenera ndi chisamaliro, maginito a neodymium amatha kukhala kwa nthawi yayitali, ndipo nthawi zambiri kuposa maginito ena.
Kuti muchulukitse moyo wa maginito a neodymium, ndikofunikira kuyisunga bwino, kuyisunga kutali ndi maginito ena omwe angakhudze mphamvu yake ya maginito, ndikupewa kuyika kutentha kwambiri kapena mphamvu zamaginito. Kuphatikiza apo, maginito a neodymium amayenera kugwiridwa mosamala, chifukwa ndi olimba ndipo amatha kusweka kapena kusweka ngati atagwetsedwa kapena kugwiridwa molakwika.

4.Kodi zinthu zina zabwino zomwe ndingachite ndi neodymium maginito?
Maginito a Neodymium ndi amphamvu kwambiri komanso osinthasintha, ndipo pali zinthu zambiri zabwino zomwe mungachite nawo. Nawa malingaliro angapo:
Pangani chipangizo cholumikizira maginito: Mutha kugwiritsa ntchito maginito a neodymium kuti mupange chipangizo chosavuta cholumikizira, pomwe maginito amayimitsidwa mlengalenga pamwamba pa maginito ena. Uku kungakhale kuyesa kosangalatsa komanso kochititsa chidwi kuwonetsa mphamvu ya maginito a neodymium.
Pangani choyatsira maginito: Maginito a Neodymium atha kugwiritsidwa ntchito kupanga cholumikizira maginito pazoyeserera zasayansi kapena kufungira moŵa kunyumba. Poyika maginito mumtsuko wamadzimadzi ndikugwiritsanso ntchito maginito yachiwiri pansi pa chidebecho, mutha kupanga chokondoweza popanda kufunikira kusonkhezera madziwo.
Kumanga amaginito motor: Maginito a Neodymium angagwiritsidwe ntchito kupanga injini yosavuta yomwe imayenda pa mphamvu ya maginito m'malo mwa magetsi. Izi zitha kukhala ntchito yosangalatsa komanso yophunzitsa kwa ana kapena aliyense amene ali ndi chidwi ndi zamagetsi.
Pangani zodzikongoletsera za maginito: Maginito a Neodymium amatha kuphatikizidwa muzojambula zodzikongoletsera, monga zibangili za maginito, mikanda, kapena ndolo. Izi zitha kupereka chowonjezera chapadera komanso chowoneka bwino komanso kugwiritsa ntchito mwayi wamachiritso a maginito.
Pangani maginitomasewera a nsomba: Maginito a Neodymium angagwiritsidwe ntchito popanga masewera osodza osangalatsa, pomwe maginito amamangiriridwa kumapeto kwa mizere ya nsomba ndipo amagwiritsidwa ntchito "kugwira" zinthu zachitsulo mumtsuko wamadzi.
Pangani maginito Castle ndiMipira yamagetsi ya NdFeB: pali mitundu yambiri ya mipira ya maginito ya NdFeB pamsika lero. Mipira yamaginito ya NdFeB iyi nthawi zambiri imakhala yokongola komanso maginito, ndipo ina imakhala yokutidwa ndi utoto wonyezimira-mu-mdima. Kaya mukufuna kusewera nawo nokha kapena kuwagwiritsa ntchito ndi mwana wanu kuti muwathandize kukulitsa luso lawo, ndi chisankho chabwino kwambiri.
5.Chifukwa chiyani maginito a neodymium ali amphamvu kwambiri?
Maginito a Neodymium ndi amphamvu kwambiri chifukwa cha kuphatikiza kwawo kwapadera kwa zinthu ndi mawonekedwe a kristalo.
Maginito a Neodymium amapangidwa ndi aloyi ya neodymium, chitsulo, ndi boron, ndipo chinthu cha neodymium ndi chitsulo chosowa padziko lapansi chomwe chimadziwika ndi mphamvu zake zolimba za maginito. Kuphatikiza pa neodymium, aloyiyo imakhala ndi zinthu zina zapadziko lapansi zomwe sizipezeka, monga dysprosium, terbium, kapena praseodymium, zomwe zimathandizira kukulitsa mphamvu ya maginito ya zinthuzo.
Kapangidwe ka kristalo ka maginito a neodymium ndi chinthu chofunikira pa mphamvu zawo. Makhiristowo amagwirizanitsidwa mwanjira inayake panthawi yopanga, zomwe zimathandiza kuti pakhale mphamvu yamphamvu komanso yosagwirizana ndi maginito. Njira yolumikizira iyi imadziwika kuti "sintering", yomwe imaphatikizapo kutentha ndi kukanikiza ufa wa neodymium alloy mu chipika cholimba.
Zotsatira za zinthuzi ndi maginito omwe ali ndi mphamvu yamphamvu kwambiri yomwe imatha kukopa kapena kuthamangitsa maginito ena patali. Izi zimapangitsa maginito a neodymium kukhala abwino kwa ntchito zosiyanasiyana, kuchokera kumakina amakampani kupita kumagetsi ogula. Komabe, mphamvu zawo zimatanthauzanso kuti ayenera kusamaliridwa mosamala, chifukwa akhoza kuwononga mosavuta zipangizo zamagetsi kapena kutsina zala ngati zikugwiritsidwa ntchito molakwika.
