(Demagnetization Curves for N40UH Neodymium Magnet)
Maginito akhala akuchititsa chidwi anthu kwa zaka mazana ambiri, kusonyeza mphamvu zochititsa chidwi zimene zimaoneka kukhala zosamvetsetseka. Pakatikati pa mphamvu ya maginito pali phiri la demagnetization, lingaliro lofunikira pakumvetsetsa maginito ake. Mu positi iyi yabulogu, tikuyamba ulendo wochotsa ma curve a demagnetization, kuwulula zinsinsi zomwe zimamanga ndi kufunika kwake pamagwiritsidwe osiyanasiyana. Chifukwa chake, tiyeni tilowe mu dziko la magnetism ndikuwona chodabwitsa ichi!
Demagnetization curve yalengezedwa
Mkhope wa demagnetization, womwe umadziwikanso kuti curve ya magnetization kapena hysteresis loop, umawonetsa machitidwe azinthu zamaginito zikakhudzidwa ndi kusintha kwa maginito. Imawonetsa mgwirizano pakati pa mphamvu ya maginito ndi kulowetsedwa kwa maginito kapena kuchulukitsitsa. Pokonza mphamvu ya maginito (H) pa x-axis ndi magnetic flux density (B) pa y-axis, ma curve demagnetization amatilola kumvetsetsa ndi kusanthula maginito azinthu.
Kumvetsetsa Makhalidwe a Magnetic Materials
Poyang'ana ma curve a demagnetization, titha kuzindikira magawo ofunikira omwe amatanthawuza momwe zinthu zimagwirira ntchito m'magawo osiyanasiyana a maginito. Tiyeni tione mbali zitatu zofunika:
1. Machulukitsidwe mfundo: Poyambirira, pamapindikira otsetsereka kwambiri mpaka kufika pachimake, pomwe palibe kuwonjezeka kwa mphamvu ya maginito kungakhudze kuchuluka kwa flux. Mfundo imeneyi imasonyeza kukhuta kwa zinthu. Zida zosiyanasiyana zimakhala ndi machulukitsidwe osiyanasiyana, zomwe zimayimira kuthekera kwawo kukhalabe maginito pansi pa maginito amphamvu.
2. Kukakamizika: Kupitilira pamphepete, mphamvu ya maginito imachepa, zomwe zimapangitsa kuchepa kwa mphamvu ya maginito. Komabe, zinthuzo zikakhalabe ndi magnetization, padzakhala pomwe pamapindikira amadutsa x-axis. Njirayi ikuyimira mphamvu yokakamiza, kapena mphamvu yokakamiza, yomwe imasonyeza kukana kwa zinthu ku demagnetization. Zida zokakamiza kwambiri zimagwiritsidwa ntchito mu maginito osatha kapena maginito ena okhazikika.
3. Kukhazikika: Pamene mphamvu ya maginito ifika pa ziro, phirilo limadutsa pakati pa y-axis kuti ipatse mphamvu ya remanence flux kapena remanence. Parameter iyi ikuwonetsa momwe zinthuzo zimakhalira maginito ngakhale maginito akunja atachotsedwa. Kukhazikika kwakukulu ndikofunikira pamapulogalamu omwe amafunikira machitidwe okhalitsa a maginito.
Kugwiritsa Ntchito ndi Kufunika
Ma curve a Demagnetization amapereka chidziwitso chofunikira pakusankha kwazinthu ndi kukhathamiritsa kwazinthu zosiyanasiyana. Nazi zitsanzo zofunika:
1. Ma motors: Kudziwa mapindikidwe a demagnetization kumathandizira kupanga ma mota abwino okhala ndi zida zokongoletsedwa ndi maginito zomwe zimatha kupirira maginito apamwamba popanda demagnetization.
2. Kusungirako deta ya maginito: Mapiritsi a demagnetization amathandiza akatswiri kupanga makina ojambulira maginito abwino kwambiri okhala ndi mphamvu zokwanira zosungirako zodalirika komanso zokhazikika.
3. Zipangizo zamagetsi: Kupanga ma inductor cores ndi ma transfoma kumafunika kuwunika mosamala ma curve a demagnetization kuti agwirizane ndi zofunikira zamagetsi ndi makina.
Mapeto
Lowani kudziko la maginito kudzera mu ma lens a demagnetization curves, kuwulula zovuta zamachitidwe amagetsi ndi momwe amagwiritsidwira ntchito. Pogwiritsa ntchito mphamvu yokhotakhotayi, mainjiniya akukonza njira yopititsira patsogolo zinthu zatsopano m'magawo osiyanasiyana, ndikuwongolera luso lamakono lamtsogolo. Chifukwa chake nthawi ina mukakumana ndi maginito, tengani kamphindi kuti mumvetsetse sayansi yomwe ili kumbuyo kwa maginito ake ndi zinsinsi zobisika mumayendedwe osavuta a demagnetization.
