Magnetị Neodymium na Magnetị Hematite bụ ihe magnet abụọ a na-ahụkarị, nke a na-ejikarị eme ihe n'ọhịa ha. Magnetị Neodymium bụ nke Rare-earth magnet, nke mejupụtara neodymium, iron, boron na ihe ndị ọzọ. O nwere ike magnetism siri ike, ike nrụgide na nguzogide nchara, a na-ejikwa ya nke ukwuu na moto, jenerato, akụrụngwa acoustic na ubi ndị ọzọ. Magnetị Hematite bụ ụdị ihe magnetik nke e ji ígwè mee, nke a na-ejikarị hematite nwere ígwè eme. O nwere ihe magnetik na mgbochi nchacha, a na-ejikwa ya eme ihe na ihe magnetik ọdịnala, ngwa nchekwa data na ubi ndị ọzọ.N'isiokwu a, a ga-atụle njirimara na ojiji nke Neodymium magnet na Hematite magnet n'ụzọ miri emi, a ga-atụnyere ọdịiche ha.

Ⅰ.Agwa na ojiji nke Neodymium magnet:

A. Àgwà nke magnet Neodymium:

Ngwakọta kemịkalụ:Magnetị Neodymium nwere neodymium (Nd), iron (Fe) na ihe ndị ọzọ. Ọdịnaya nke neodymium na-adịkarị n'etiti 24% na 34%, ebe ọdịnaya nke ígwè bụ ihe ka ọtụtụ. Na mgbakwunye na neodymium na iron, magnet Neodymium nwekwara ike ịnwe ụfọdụ ihe ndị ọzọ, dị ka boron (B) na ihe ndị ọzọ dị ụkọ n'ụwa, iji melite njirimara magnet ya.

Ịdọta:Magnetị Neodymium bụ otu n'ime magnet azụmahịa kachasị ike a maara ugbu a. O nwere magnetization dị elu nke ukwuu, nke nwere ike iru ọkwa magnet ndị ọzọ na-enweghị ike iru. Nke a na-enye ya njirimara magnet dị mma ma dabara nke ọma maka ngwa ndị chọrọ magnetization dị elu.

Mmanye:Magnetị Neodymium nwere oke Coercivity, nke pụtara na ọ nwere ike iguzogide ike ndọta na iguzogide nkụ. N'iji ya, magnet Neodymium nwere ike idobe ọnọdụ magnetization ya ma ọ naghị emetụta ya ngwa ngwa site na ike ndọta mpụga.

Mgbochi nrụrụ aka:Nguzogide nchara nke magnet Neodymium adịghị mma, yabụ ọgwụgwọ elu, dịka electroplating ma ọ bụ ọgwụgwọ okpomọkụ, na-achọkarị iji melite iguzogide nchara ya. Nke a nwere ike ime ka magnet Neodymium ghara ịdị mfe iji ya mee ihe.

B. Ojiji nke Neodymium magnet:

Moto na jenerato: A na-ejikarị magnet Neodymium eme ihe n'ọtụtụ ebe n'ime moto na jenereta n'ihi nnukwu magnetization na Coercivity ya. Magneti Neodymium nwere ike inye ike magnet siri ike, nke mere na moto na jenereta nwere ike ịrụ ọrụ nke ọma ma rụọ ọrụ nke ọma.

Ngwa Akustik: A na-ejikwa magnet Neodymium eme ihe na ngwa akustik, dịka igwe okwu na ekweisi. Ọdụ magnet ya dị ike nwere ike imepụta ụda dị elu ma nwee mmetụta ụda ka mma. Ngwa ahụike: A na-ejikwa magnet Neodymium eme ihe nke ukwuu na ngwa ahụike. Dịka ọmụmaatụ, na ngwa magnet resonance imaging (MRI), magnet Neodymium nwere ike imepụta oghere magnet kwụsiri ike ma nye onyonyo dị elu.

Ụlọ ọrụ ụgbọelu: N'ime ụlọ ọrụ ụgbọelu, a na-eji magnet Neodymium emepụta usoro njem na njikwa ụgbọelu, dịka gyroscope na steering gia. Ọ na-eme ka magnetization na corrosion sie ike nke ukwuu, na-eme ka ọ bụrụ nhọrọ kacha mma.

Na mmechi, n'ihi ihe mejupụtara kemịkalụ pụrụ iche ya na njirimara ya dị mma,Neodymium magnet ụwa dị ụkọỌ na-arụ ọrụ dị mkpa n'ọtụtụ ebe eji eme ihe, ọkachasị n'igwe eletriki, akụrụngwa acoustic, akụrụngwa ahụike na ụlọ ọrụ ụgbọ elu. Ọ dịkwa mkpa iji hụ na arụmọrụ na ndụ nkeMagnet pụrụ iche nke Neodymium, chịkwaa mgbanwe okpomọkụ ya ma mee ihe ndị kwesịrị ekwesị iji gbochie ire ere.

Ⅱ. Njirimara na ojiji nke magnet Hematite:

A. Àgwà nke ndọta Hematite:

Ngwakọta kemịkalụ:Ihe mejupụtara Hematite magnet bụ ígwè, nke nwere iron oxide na ihe ndị ọzọ na-adịghị mma. Isi ihe mejupụtara ya bụ Fe3O4, nke bụ iron oxide.

Ịdọta: Igwe ndọta Hematite nwere ike ịrụ ọrụ nke ọma ma bụrụkwa nke ihe ndọta na-adịghị ike. Ọ bụrụ na e nwee ebe ndọta na-adịghị ike, igwe ndọta Hematite ga-emepụta magnetism ma nwee ike ịdọta ụfọdụ ihe ndọta.

Mmanye: Igwe ndọta Hematite nwere obere Coercivity, ya bụ, ọ chọrọ obere ebe ndọta mpụga iji mee ka ọ dị ka magnet. Nke a na-eme ka ndọta Hematite dị mfe ma dịkwa mfe iji rụọ ọrụ na ụfọdụ ngwa.

Mgbochi nrụrụ aka: Igwe ndọta Hematite na-adịgide adịgide n'ebe kpọrọ nkụ, mana ọ na-emebi emebi n'ebe mmiri dị ma ọ bụ ebe iru mmiri dị. Ya mere, n'oge ụfọdụ, magnet Hematite chọrọ ọgwụgwọ ma ọ bụ mkpuchi elu iji mee ka iguzogide nchara ha ka mma.

B. Ojiji nke ihe ndọta Hematite

Ihe ndọta ọdịnala: A na-ejikarị magnet Hematite eme ihe magnet ọdịnala, dịka magnet friji, sticker magnet, wdg. N'ihi magnetism ya dị oke mma na obere Coercivity, magnet Hematite dị mfe ịmịnye n'elu ígwè ma ọ bụ ihe magnet ndị ọzọ, a pụkwara iji ya mee ihe maka idozi ihe, ihe anụ ahụ na ngwa ndị ọzọ.

Ngwa nchekwa data:Igwe ndọta Hematite nwekwara ụfọdụ ngwa na akụrụngwa nchekwa data. Dịka ọmụmaatụ, na draịvụ diski ike, a na-eji igwe ndọta Hematite eme akwa ndọta n'elu diski maka ịchekwa data.

Ngwa onyonyo ahụike: A na-ejikwa magnet Hematite eme ihe nke ukwuu n'ihe gbasara onyonyo ahụike, dịka sistemụ onyonyo magnetik resonance (MRI). Enwere ike iji magnet Hematite mee ihe dị ka ihe na-emepụta ubi magnetik na sistemụ MRI iji mepụta ma chịkwaa ubi magnetik, si otú a na-ahụ na e sere foto nke anụ ahụ mmadụ.

Mmechi: Igwe ndọta Hematite nwere ike ịrụ ọrụ nke ọma, ọ na-ebelata nrụgide na ụfọdụ nguzogide nchara. O nwere ọtụtụ ojiji na mmepụta ihe ndọta ọdịnala, ngwaọrụ nchekwa data, na onyonyo ahụike. Agbanyeghị, n'ihi oke ndọta na arụmọrụ ya, ndọta Hematite adịghị mma maka ụfọdụ ngwa chọrọ ndọta na ihe achọrọ maka arụmọrụ dị elu.

E nwere ihe dị iche n'etiti magnet Neodymium na magnet Hematite n'ihe mejupụtara kemịkalụ, ihe onwunwe magnet na ubi ngwa.Ihe mejupụtara neodymium magnet bụ neodymium na ígwè, yana magnetism siri ike na oke Coercivity. A na-ejikarị ya eme ihe n'ọhịa dịka ngwaọrụ draịva magnet, magnet, buckles magnet, na moto arụmọrụ dị elu. N'ihi na neodymium magnet nwere ike imepụta ike magnet siri ike, ọ nwere ike ịgbanwe ike na ike eletrik, nye ike magnet dị irè, ma melite ike na arụmọrụ nke moto ahụ.Ihe mejupụtara magnet Hematite bụ ígwè, ihe mejupụtara ya bụ Fe3O4. Ọ nwere magnetism dị mma na obere Coercivity. A na-ejikarị magnet Hematite eme ihe n'ọtụtụ ebe n'ichepụta ihe magnet ọdịnala na ụfọdụ ngwa onyonyo ahụike. Agbanyeghị, iguzogide nchara nke magnet Hematite adịghị mma, a chọkwara ọgwụgwọ ma ọ bụ mkpuchi elu iji mee ka iguzogide nchara ha dịkwuo mma.

Na mkpokọta, enwere ihe dị iche n'etiti magnet Neodymium na magnet Hematite na ihe mejupụtara kemịkalụ, ihe onwunwe magnet na ubi ngwa. Magnetị Neodymium dabara na ubi chọrọ ike magnet na oke nrụgide, ebe magnet Hematite dabara na mmepụta ihe magnet ọdịnala na ụfọdụ ngwa onyonyo ahụike. Ọ bụrụ na ịchọrọ ịzụtamagnet iko neodymium nke na-eguzogide mmiribiko kpọtụrụ anyị ozugbo. Ụlọ ọrụ mmepụta ihe anyị nwere ọtụtụMagnet neodymium ndị na-adịghị mma maka ọrịre.
