Ⅰ. Njirimara magnetik nke Neodymium magnet na ụkpụrụ nke mgbanwe okpomọkụ

A. Njirimara magnetik bụ isi nke magnet Neodymium: Magnetị Neodymium bụ ụdị ihe ndọta ụwa na-adịghị ahụkebe nke nwere nnukwu ihe ndọta siri ike. O nwere njirimara nke ngwaahịa ike ndọta dị elu, nchekwa dị elu na oke nrụgide. Ike ubi ndọta Neodymium na-adịkarị elu karịa nke magnet ferrite na aluminum nickel cobalt. Nke a na-eme ka magnet Neodymium dị ọtụtụ n'ọtụtụ ngwa, dị ka moto, sensọ na magnet.

B. Mmekọrịta dị n'etiti nhazi atọm na oge ndọta:A na-ahụta magnetism nke Neodymium site na mmekọrịta nke oge magnetik atọm. Oge magnetik atọm mejupụtara ntụgharị nke elektrọn na oge magnetik orbital. Mgbe a haziri atọm ndị a na lattice, mmekọrịta oge magnetik ha na-eduga n'ọdịpụta nke magnetism. Na magnet Neodymium, oge magnetik nke atọm na-esitekarị na ion neodymium asaa na-enweghị njikọ, nke ntụgharị ha dị n'otu ụzọ ahụ dị ka oge magnetik orbital. N'ụzọ dị otu a, a na-emepụta oghere magnetik siri ike, na-ebute magnetism siri ike nke magnet Neodymium siri ike.

C. Mmetụta nke mgbanwe okpomọkụ na nhazi atọm: A na-ekpebi nhazi na mmekọrịta nke atọm n'ime lattice site na okpomọkụ. Ka okpomọkụ na-abawanye, mmegharị okpomọkụ nke atọm na-abawanye, mmekọrịta dị n'etiti atọm na-ebelatakwa nke ukwuu, nke na-eduga na enweghị nguzozi nke nhazi nke atọm n'usoro. Nke a ga-emetụta nhazi atọm nke magnet Neodymium, si otú a na-emetụta ihe onwunwe magnet ya. N'oge okpomọkụ dị elu, mmegharị okpomọkụ nke atọm na-esikwu ike, mmekọrịta dị n'etiti atọm na-ebelatakwa, na-eduga na ike magnetization na magnet Neodymium na-ebelata.

D. Oke okpomọkụ magnetik dị mkpa nke Neodymium magnet:Okpomọkụ magnet dị mkpa nke magnet Neodymium na-ezo aka na okpomọkụ nke magnet Neodymium na-efunahụ magnetism ya na okpomọkụ dị elu. N'ikwu ya n'ozuzu, okpomọkụ magnet dị mkpa nke magnet Neodymium dị ihe dị ka 200-300 ℃. Mgbe okpomọkụ gafere okpomọkụ magnet dị mkpa, nhazi atọm nke magnet Neodymium na-emebi, a na-ekesakwa ntụziaka oge magnet na-enweghị usoro, na-ebute mbelata ma ọ bụ ọbụna ọnwụ zuru oke nke magnetization na ike magnet. Ya mere, n'iji ya, a ga-elebara anya na ijikwa okpomọkụ ọrụ nke magnet Neodymium iji nọgide na-enwe njirimara magnet siri ike ya.

Ⅱ. Mmetụta nke okpomọkụ na magnetism nke Neodymium magnet

A. Mmetụta nke mgbanwe okpomọkụ na magnetization nke Neodymium magnet:Mgbanwe okpomọkụ ga-emetụta magnetization nke Neodymium magnet. N'ozuzu, ka okpomọkụ na-abawanye, magnetization nke Neodymium magnet ga-ebelata, usoro magnetization ga-adịkwa larịị. Nke a bụ n'ihi na okpomọkụ dị elu ga-eme ka mpaghara magnet dị na Neodymium magnet ghara ịdị mma, na-ebute mbelata na magnetization nkeobere magnet diski neodymium.

B. Mmetụta nke mgbanwe okpomọkụ na Coercivity nke Neodymium magnet: Ike na-ezo aka na ike ike ndọta etinyere na-eru uru dị mkpa nke magnetization zuru oke nke magnet n'oge magnetization. Mgbanwe nke okpomọkụ ga-emetụta Ike ndọta Neodymium. N'ozuzu, na okpomọkụ dị elu, Ike ndọta Neodymium ga-ebelata, ebe na okpomọkụ dị ala, Ike ndọta ga-abawanye. Nke a bụ n'ihi na okpomọkụ dị elu nwere ike ime ka mkpali okpomọkụ nke ngalaba ndọta dịkwuo elu, na-achọ obere oghere ndọta iji magnetization dum.

C. Mmetụta nke mgbanwe okpomọkụ na mwepu oge na ịnọgide na-enwe Neodymium magnet: Mbelata oge na-ezo aka n'ọkwa mbelata nke oge magnet n'oge magnetization nke magnet, na ịnọgide na-enwe ike na-ezo aka n'ọkwa magnetization nke magnet Neodymium ka nwere n'okpuru mmetụta nke demagnetization. Mgbanwe nke okpomọkụ ga-emetụta mwepụ oge na ịnọgide na-enwe nke magnet Neodymium. N'ikwu ya n'ozuzu, mmụba na okpomọkụ ga-eduga na mmụba na mbelata oge nke magnet neodymium, na-eme ka usoro magnetization dịkwuo ngwa ngwa. N'otu oge ahụ, mmụba nke okpomọkụ ga-ebelatakwa ịnọgide na-enwe nke magnet Neodymium, na-eme ka ọ dịkwuo mfe ịkwụsị magnetization n'okpuru ọrụ nke demagnetization.

Ⅲ.Ngwa na njikwa nke Neodymium magnet magnet ọnwụ

A. Oke okpomọkụ maka ojiji nke Neodymium magnet: Oke okpomọkụ ga-emetụta ihe ndọta nke ndọta Neodymium, yabụ ọ dị mkpa ịkpa oke okpomọkụ ọrụ nke ndọta Neodymium n'ọrụ bara uru. N'ikwu ya n'ozuzu, okpomọkụ ọrụ nke ndọta Neodymium kwesịrị ịdị ala karịa okpomọkụ ndọta ya iji hụ na arụmọrụ ndọta kwụsiri ike. Oke okpomọkụ ọrụ akọwapụtara ga-adị iche dabere na ngwa dị iche iche na ihe ndị akọwapụtara. A na-atụ aro ka ejiri ndọta Neodymium dị n'okpuru 100-150 ℃.

B. Ntụle nke okpomọkụ na ike magnetik na nhazi magnet: Mgbe a na-emepụta magnet, mmetụta nke okpomọkụ na ike magnet bụ ihe dị mkpa a ga-atụle. Oke okpomọkụ ga-ebelata ike magnet nke Neodymium magnet, yabụ ọ dị mkpa ịtụle mmetụta nke okpomọkụ ọrụ na usoro nhazi. Ụzọ a na-ahụkarị bụ ịhọrọ ihe magnet nwere ezigbo nkwụsi ike okpomọkụ, ma ọ bụ mee ihe ndị na-ajụ oyi iji belata okpomọkụ ọrụ nke magnet iji hụ na ọ nwere ike ịnọgide na-enwe ike magnet zuru oke na gburugburu okpomọkụ dị elu.

C. Ụzọ iji melite nkwụsi ike okpomọkụ nke Neodymium magnet: Iji melite nkwụsi ike okpomọkụ nke Neodymium magnet na okpomọkụ dị elu, enwere ike iji usoro ndị a: Ịtinye ihe alloy: itinye ihe alloy dị ka aluminom na nickel na Neodymium magnet nwere ike ime ka iguzogide okpomọkụ dị elu ka mma. Ọgwụgwọ mkpuchi elu: ọgwụgwọ pụrụ iche n'elu Neodymium magnet, dị ka electroplating ma ọ bụ mkpuchi oyi akwa nke ihe nchebe, nwere ike ime ka iguzogide okpomọkụ dị elu ka mma. Nhazi nhazi Magnet: site na ime ka nhazi na geometry nke magnet ahụ dịkwuo mma, enwere ike ibelata mmụba okpomọkụ na mfu okpomọkụ nke Neodymium magnet na okpomọkụ dị elu, si otú a na-eme ka nkwụsi ike okpomọkụ ka mma. Usoro oyi: usoro oyi kwesịrị ekwesị, dị ka mmiri oyi ma ọ bụ oyi fan, nwere ike ibelata okpomọkụ ọrụ nke Neodymium magnet ma melite nkwụsi ike okpomọkụ ya. Ọ dị mkpa ịmara na ọ bụ ezie na enwere ike ime ka nkwụsi ike okpomọkụ nke Neodymium magnet dịkwuo mma site na usoro ndị dị n'elu, magnetism nke Neodymium magnet nwere ike ịla n'iyi na gburugburu okpomọkụ dị oke elu ma ọ bụrụ na agafee okpomọkụ magnet dị oke mkpa ya. Ya mere, na ngwa okpomọkụ dị elu, a ga-atụle ihe ndị ọzọ ma ọ bụ ihe ndị ọzọ iji mezuo ọchịchọ ahụ.

Na ngwụcha

Nkwụsi ike nke okpomọkụ nke magnet Neodymium dị oke mkpa iji nọgide na-enwe njirimara magnet na mmetụta ojiji ya. Mgbe ị na-emepụta ma na-ahọrọ magnet Neodymium, ọ dị mkpa ịtụle njirimara magnetization ya na oke okpomọkụ akọwapụtara ma mee ihe ndị kwekọrọ na ya iji mee ka arụmọrụ ya kwụsie ike.
