Maginito Akuluakulu a Neodymium Disc – Mayankho Apadera | Fullzen

Maginito akuluakulu a neodymium omwe amapezeka pamsika nthawi zambiri amakhala ngati block kapena disc magnet, okhala ndi miyeso kuyambira mainchesi angapo mpaka mainchesi angapo m'litali ndi m'lifupi. Maginito akuluakulu a neodymium awa amatha kukhala ndi mphamvu yokoka ya maginito ndipo amagwiritsidwa ntchito pazinthu zosiyanasiyana monga zida zamafakitale, zolekanitsa maginito, ma mota, ndi majenereta. Ngakhale palibe malire enieni a kukula kwa maginito a neodymium, ndikofunikira kudziwa kuti pamene kukula kukuwonjezeka, mphamvu ya maginito ya maginito ikhoza kuchepa. Izi zili choncho chifukwa maginito akuluakulu akhoza kukhala ndi mwayi waukulu woti maginito amkati azisiyana, zomwe zimachepetsa mphamvu yawo yonse ya maginito. Komabe, kupita patsogolo kwa njira zopangira maginito kwalola kuti maginito akuluakulu a neodymium akhale ndi mphamvu zabwino zamaginito.

Maginito a Neodymium disc, omwe amadziwikanso kuti maginito ozungulira a neodymium kapena maginito a neodymium silinda, ndi maginito ang'onoang'ono ooneka ngati cylindrical opangidwa kuchokera ku neodymium-iron-boron (NdFeB) alloy. Ndi maginito amphamvu kwambiri okhazikika omwe amapezeka pamsika. Maginito awa nthawi zambiri amapangidwa ngati diski, pomwe mainchesi ake ndi akulu kuposa kutalika (kukhuthala), zomwe zimapangitsa kuti akhale ozungulira. Amabwera m'makulidwe osiyanasiyana, okhala ndi mainchesi ndi makulidwe kuyambira mamilimita angapo mpaka mainchesi angapo. Chifukwa cha mphamvu yawo yayikulu ya maginito, maginito a neodymium disc amagwiritsidwa ntchito kwambiri m'njira zosiyanasiyana, kuphatikiza zamagetsi, zida zamankhwala, mafakitale amagalimoto, ntchito zamanja ndi zosangalatsa, kutseka kwa maginito, zodzikongoletsera zamaginito, komanso ngakhale mu kuyesa kwa maginito. Popeza ndi ang'onoang'ono komanso mphamvu yamphamvu yamaginito, amafunika kusamalidwa mosamala chifukwa amatha kukoka kapena kuthamangitsa zinthu zina zamaginito ndipo angayambitse kuvulala ngati atagwiritsidwa ntchito molakwika.

"N" mu neodymium imatanthauza chizindikiro cha mankhwala cha chinthu cha neodymium. Neodymium (Nd) ndi chinthu chosowa chapadziko lapansi chomwe chili mu mndandanda wa lanthanide wa tebulo la periodic. Dzina lake limatchedwa kuchokera ku mawu achi Greek "neos" kutanthauza "yatsopano" ndi "didymos" kutanthauza "mapasa," zomwe zikusonyeza kupezeka kwake ngati chinthu chapawiri ku chinthu chodziwika kale, praseodymium. Neodymium imagwiritsidwa ntchito kwambiri popanga maginito amphamvu okhazikika, monga maginito a neodymium, chifukwa cha mphamvu zake zamaginito apamwamba. Chinthuchi chimathandizira ku mphamvu yamphamvu yamaginito yomwe imawonetsedwa ndi maginito a neodymium, zomwe zimapangitsa kuti azifunidwa kwambiri m'njira zosiyanasiyana zomwe zimafuna mphamvu yamphamvu yamaginito.
