Kupambana kwatsopano mu dziko la maginito

Zatsopano zapadziko lapansi za maginito zikulonjeza kupita patsogolo kosintha masewera m'mafakitale osiyanasiyana. Maginito osowa padziko lapansi, makamaka maginito a neodymium, akuyang'ana kwambiri posachedwapa chifukwa cha ubwino omwe amapereka pa maginito achikhalidwe.

Maginito a Neodymium, omwe amatchedwanso maginito a NdFeB, ndi mtundu wa maginito osowa padziko lapansi omwe amadziwika chifukwa cha mphamvu zawo zapadera komanso maginito. Amapangidwa kuchokera ku neodymium, iron, ndi boron, ndipo ali ndi mphamvu ya maginito yomwe imakhala yamphamvu kuwirikiza ka 25 kuposa maginito achikhalidwe.

Kugwiritsidwa ntchito kwakukulu kwa maginito a neodymium ndi m'makampani azachipatala, komwe amagwiritsidwa ntchito pamakina a magnetic resonance imaging (MRI) chifukwa chotha kupanga maginito amphamvu. Ukadaulo uwu wasintha momwe madokotala amazindikirira ndi kuchiritsa odwala, ndikupereka njira zolondola komanso zosasokoneza zomwe zimapangitsa kuti zotsatira za odwala zikhale bwino.

Kugwiritsiranso ntchito kwina kwakukulu kwa maginito a neodymium kuli m'makampani amagalimoto. Maginitowa amagwiritsidwa ntchito m'magalimoto amagetsi, makamaka m'galimoto zosakanizidwa ndi zamagetsi. Mphamvu ndi mphamvu za maginito a neodymium zimapangitsa kuti magalimotowa azithamanga kwambiri komanso kuti aziyenda motalikirapo, zomwe ndizofunikira chifukwa anthu ochulukirachulukira amatenga magalimoto opanda mphamvu.

Mafakitale ena omwe amapezerapo mwayi pa maginito a neodymium akuphatikiza zamagetsi zamagetsi, zamlengalenga, komanso kupanga mphamvu. Pamagetsi, maginito a neodymium amagwiritsidwa ntchito mu mahedifoni, oyankhula, ndi ma hard disk drive chifukwa cha kukula kwawo kophatikizana komanso mphamvu yamaginito. Muzamlengalenga, maginitowa amagwiritsidwa ntchito mu masensa ndi ma avionics, komwe ukadaulo wopepuka komanso wodalirika ndiofunikira. Popanga mphamvu, maginito a neodymium amagwiritsidwa ntchito m'magalasi amphepo, omwe amapanga mphamvu zoyera pamtengo wotsikirapo kuposa mafuta achilengedwe.

Ngakhale zabwino zake, maginito a neodymium sakhala opanda zovuta zawo. Chodetsa nkhaŵa chimodzi ndi kukwera mtengo kwawo, komwe kuli chifukwa cha kusoŵa kwa zipangizo zomwe zimagwiritsidwa ntchito popanga. Kuonjezera apo, maginitowa ndi ophwanyika kwambiri ndipo amatha kuwonongeka mosavuta ngati sanagwire bwino. Komabe, makampani akuika ndalama pa kafukufuku kuti athe kuthana ndi zovutazi ndikupeza njira zopangira maginito a neodymium kukhala ofikirika komanso osavuta kugwiritsa ntchito.

Ponseponse, kupita patsogolo kwaposachedwa kwa maginito osowa padziko lapansi, makamaka maginito a neodymium, ndizochitika zosangalatsa zomwe zimatha kusintha mafakitale ambiri. Ngakhale pali zovuta zomwe muyenera kuthana nazo, zopindulitsa za maginitowa zimawapangitsa kukhala njira yofunikira yopangira zatsopano komanso kupita patsogolo.
