Maginito a Neodymium, omwe amadziwikanso kuti NdFeB kapena maginito osowa padziko lapansi, akhala mwala wapangodya waukadaulo wamakono. Ulendo wawo wochoka pakupanga zinthu kupita ku ntchito zofala ndi umboni wa luntha laumunthu ndi kufunafuna kosalekeza kwa zipangizo zogwira mtima ndi zamphamvu.

Kupangidwa kwa Magnet a Neodymium

Maginito a Neodymium adapangidwa koyambirira kwa zaka za m'ma 1980 chifukwa choyesetsa kupanga maginito amphamvu okhazikika. Kupangaku kunali ntchito yothandizana pakati pa General Motors ndi Sumitomo Special Metals. Ofufuza anali kufunafuna maginito omwe angalowe m'malo mwa maginito a samarium-cobalt, omwe anali amphamvu koma okwera mtengo komanso ovuta kupanga.

Kupambanaku kudabwera ndikupeza kuti aloyi ya neodymium, iron, ndi boron (NdFeB) imatha kupanga maginito okhala ndi mphamvu zokulirapo pang'ono pamtengo wake. Maginito atsopanowa sanali amphamvu kwambiri kuposa oyambirira komanso ochuluka kwambiri chifukwa cha kupezeka kwa neodymium poyerekeza ndi samarium. Maginito oyamba amalonda a neodymium adapangidwa mu 1984, zomwe zikuwonetsa kuyamba kwa nyengo yatsopano mu maginito.

Chitukuko ndi Chitukuko

Kwa zaka zambiri, kupita patsogolo kwakukulu kwachitika pakupanga ndi kukonzanso maginito a neodymium. Mabaibulo oyambirira ankatha kuwononga komanso anali ndi kutentha kochepa kwambiri. Pofuna kuthana ndi vutoli, opanga amapanga zokutira zosiyanasiyana, monga faifi tambala, zinki, ndi epoxy, kuti ateteze maginito kuti asawononge chilengedwe. Kuphatikiza apo, kupita patsogolo pakupanga kwapangitsa kuti pakhale maginito okhala ndi kulolerana kolondola komanso kukhazikika kwamphamvu kwa maginito.

Kukula kwa maginito omangidwa a neodymium, omwe amaphatikiza tinthu tating'onoting'ono ta NdFeB mu matrix a polima, kwakulitsanso ntchito zosiyanasiyana. Maginito omangikawa ndi osalimba kwambiri ndipo amatha kupangidwa kukhala mawonekedwe ovuta, kupereka kusinthasintha kwapangidwe kwa mainjiniya.

Mapulogalamu Amakono

Masiku ano, maginito a neodymium amapezeka paliponse pamagwiritsidwe osiyanasiyana chifukwa cha mphamvu zawo zapamwamba komanso kusinthasintha. Zina mwazogwiritsidwa ntchito kwambiri ndi izi:

Zamagetsi:Maginito a Neodymium ndi ofunika kwambiri pazida zamakono zamakono, kuphatikizapo mafoni a m'manja, makompyuta, ndi mahedifoni. Kakulidwe kawo kakang'ono komanso mphamvu zamaginito zimawapangitsa kukhala abwino kugwiritsa ntchito zida zophatikizika, zogwira ntchito kwambiri.

Magetsi amagetsi:Kuchita bwino komanso mphamvu zamagalimoto amagetsi m'chilichonse kuyambira pazida zam'nyumba mpaka magalimoto amagetsi amadalira kwambiri maginito a neodymium. Kutha kwawo kupanga maginito amphamvu m'malo ang'onoang'ono kwasintha kamangidwe ka ma mota, zomwe zimapangitsa kuti ma mota azigwira bwino ntchito.

Zida Zachipatala:M'zachipatala, maginito a neodymium amagwiritsidwa ntchito m'makina a MRI, pacemaker, ndi zida zamagetsi zamagetsi. Maginito awo amphamvu a maginito ndi ofunika kwambiri kuti azitha kulondola komanso kudalirika komwe kumafunikira muukadaulo wazachipatala.

Mphamvu Zowonjezera:Maginito a Neodymium amagwira ntchito yofunika kwambiri popanga mphamvu zoyera. Amagwiritsidwa ntchito m'makina amphepo ndi matekinoloje ena ongowonjezwdwanso mphamvu, pomwe mphamvu zawo komanso mphamvu zawo zimathandizira kupanga mphamvu zokhazikika.

Ntchito Zamakampani:Kupitilira zamagetsi ndi zida zamankhwala, maginito a neodymium amagwiritsidwa ntchito m'mafakitale osiyanasiyana, kuphatikiza zolekanitsa maginito, makina onyamulira, ndi masensa. Kukhoza kwawo kusunga maginito pazovuta kwambiri kumawapangitsa kukhala ofunikira m'mafakitale ambiri.

Tsogolo la Magnet a Neodymium

Pomwe kufunikira kwa zida zing'onozing'ono, zogwira mtima kwambiri zikupitilira kukula, momwemonso kufunikira kwa maginito amphamvu ngati omwe amapangidwa kuchokera ku neodymium. Ochita kafukufuku panopa akufufuza njira zochepetsera kudalira zinthu zapadziko lapansi popanga ma aloyi atsopano ndi njira zopangira. Kuphatikiza apo, kubwezeredwa ndi kubweza kosasunthika kwa neodymium kukukhala kofunika kwambiri pomwe kufunikira kwapadziko lonse lapansi kukukulirakulira.

Kusintha kwa maginito a neodymium sikunathe. Ndi kafukufuku ndi chitukuko chomwe chikuchitika, maginitowa ali okonzeka kutenga gawo lofunika kwambiri pa matekinoloje amtsogolo, kuyendetsa zatsopano m'mafakitale ndikuthandizira kupita patsogolo kwa chirichonse kuchokera kumagetsi ogula mpaka mphamvu zowonjezera.
