Kuyerekeza kwa Magwiridwe Ntchito Pakati pa Maginito a Neodymium Channel ndi Mitundu Ina ya Maginito

"Ngwazi Yaikulu" ya Magnets: Chifukwa Chiyani Arc NdFeBMaginito a ChannelWamphamvu Kwambiri?

Moni nonse! Lero, tiyeni tikambirane za maginito - zinthu zazing'onozi zomwe zimaoneka ngati zachilendo koma zosangalatsa. Kodi mukudziwa? Kusiyana pakati pa maginito osiyanasiyana ndi kwakukulu ngati komwe kulipo pakati pa mafoni a m'manja ndi mafoni wamba! Makamaka maginito a NdFeB (Neodymium Iron Boron) omwe akhala akutchuka posachedwapa - kwenikweni ndi "Iron Man" wa dziko la maginito. Ndiye ndi odabwitsa bwanji? N'chiyani chimawasiyanitsa ndi maginito ena? Musadandaule, tidzakambirana pang'onopang'ono.

 

1. Kumanani ndi Banja la Magnet

Choyamba, tiyeni tifotokoze za "mabanja anayi akuluakulu" a maginito:

Maginito a NdFeB - "Opambana kwambiri" a maginito

Pakadali pano maginito amphamvu kwambiri padziko lonse lapansi

Yopangidwa ndi neodymium, chitsulo, ndi boron

Monga "omanga thupi" a maginito - amphamvu kwambiri koma amamva kutentha pang'ono

Maginito a Ferrite - "Mahatchi Ogwira Ntchito"

 

Njira yotsika mtengo kwambiri

Yopangidwa kuchokera ku iron oxide ndi strontium/barium compounds

Kukana dzimbiri bwino koma mphamvu ya maginito yofooka kwambiri

Maginito a AlNiCo - "Akatswiri akale odziwa bwino ntchito yawo"

Chimodzi mwa zipangizo zakale kwambiri zokhazikika zamaginito

Kukhazikika kwa kutentha kwabwino kwambiri

Monga othamanga okhazikika nthawi zonse omwe ali ndi luso lamphamvu loletsa kuwononga maginito

Maginito a SmCo - "Anthu apamwamba"

 

Maginito ena a rare earth opambana kwambiri

Yosagwira kutentha komanso yolimba dzimbiri

Yokwera mtengo kuposa NdFeB, imagwira ntchito ndi mapulogalamu apamwamba kwambiri

 

2. Mphamvu Zapamwamba za Maginito a NdFeB Channel

 

N’chifukwa chiyani amawatcha kuti “Iron Man”? Chifukwa ali ndi luso lodabwitsa ili:

 

Mphamvu ya Maginito Yosayerekezeka

Mphamvu yoposa maginito a ferrite nthawi 10! (Tangoganizirani wonyamula zolemera poyerekeza ndi wa kusukulu ya pulayimale)

Kubwerera m'mbuyo kumafika pa 1.0-1.4 Tesla (maginito wamba amafika pa 0.2-0.4 yokha)

Mphamvu yabwino kwambiri yolimbana ndi demagnetization, monga cockroach yosawonongeka

 

Kapangidwe ka Njira Yanzeru

Kapangidwe ka groove kamalola kulamulira bwino mphamvu ya maginito, monga kupereka magnetism GPS navigation

Yokhazikika kwambiri m'kapangidwe kake, yosachedwa kusweka ndi "kusweka"

Kukhazikitsa kosavuta, monga kusonkhanitsa mabuloko a Lego

 

Mfumu ya Magwiridwe Antchito a Mtengo

Ngakhale mtengo wa unit ndi wapamwamba kuposa wa ferrite, umapereka mtengo wotsika kwambiri pa unit iliyonse ya maginito

Zimakwaniritsa mphamvu ya maginito yolimba ndi kukula kochepa, kusunga malo ndi ndalama zonse ziwiri

 

3Kodi Muyenera Kusankha "Superhero" Yanji?

 

Sankhani Maginito a NdFeB Channel pamene:

Malo ndi ochepa koma mphamvu ya maginito ikufunika (monga ma earbuds opanda zingwe, ma motors ogwedera pafoni)

Kuwongolera bwino mphamvu ya maginito kumafunika (monga zida zamaginito, masensa)

Kuyenda pafupipafupi (monga ma EV motors, ma drone motors)

Kapangidwe kopepuka ndikofunika kwambiri (zipangizo zamlengalenga)

 

Sankhani maginito ena pamene:

Malo otentha kwambiri (oposa 200°C)

Zinthu zowononga kwambiri (zipangizo za m'mphepete mwa nyanja)

Bajeti yochepa yopangira zinthu zambiri

Zida zimakhudzidwa kwambiri ndi kusintha kwa kutentha

 

4Malangizo Ogwiritsira Ntchito Maginito a NdFeB

 

Apatseni "zovala":Chophimba pamwamba (nickel, zinc, kapena epoxy) choletsa dzimbiri

Iwo ndi "okonda galasi":Gwirani mosamala mukakhazikitsa - zimaphwanyika

Yogwirizana ndi kutentha:Kutentha kwambiri kungayambitse "kutayika kwa minofu" kosatha (demagnetization)

Malangizo ndi ofunika: Iyenera kukhala ndi maginito malinga ndi kapangidwe kake

Gwirani mosamala:Mphamvu ya maginito yolimba ingakhudze makadi a kirediti, mawotchi; sungani kutali ndi ogwiritsa ntchito makina oyeretsera mpweya

 

5Kodi Tsogolo Lili ndi Zotani?

 

Mabaibulo amphamvu:Asayansi akupanga magiredi atsopano amphamvu kwambiri

Yolimba kwambiri kutentha:Kuwapangitsa kuti asavutike kwambiri ndi kutentha kwambiri

Mapangidwe anzeru:Kugwiritsa ntchito makompyuta kuti akonze bwino kapangidwe ka njira

Mayankho obiriwiraKupititsa patsogolo ukadaulo wobwezeretsanso zinthu, kuchepetsa kugwiritsa ntchito nthaka yosowa

Zotsika mtengo kwambiri: Kukulitsa kupanga kuti ndalama zichepe

 

Maganizo Omaliza

Maginito a NdFeB ali ngati "akatswiri onse" a dziko la maginito, chisankho choyamba pa mapulogalamu ambiri apamwamba. Koma si amphamvu - monga momwe simungagwiritse ntchito galimoto yamasewera kunyamula katundu, chofunikira ndikusankha chida choyenera pantchitoyo.
