Gịnị mere magnet neodymium ga-eji tụfuo magnetism ha?

Dịka ihe dị mkpa maka magnet, magnet neodymium na-arụ ọrụ dị mkpa na teknụzụ na ụlọ ọrụ ọgbara ọhụrụ. Agbanyeghị,magnet neodymium ụlọ ọrụ mmepụta ihega-efunahụ ndọta ha n'ọnọdụ ụfọdụ kpọmkwem, nke na-eweta nsogbu ụfọdụ n'ọrụ na ojiji ha. Anyị ga-enyocha site n'echiche nke ubi ndọta mpụga, nchara kemịkalụ na oxidation, inversion domain magnet, hysteresis na ihe omume ịka nká, ma tụọ aro usoro mgbochi kwekọrọ. Site n'ịkwalite nghọta nke mgbanwe arụmọrụ nke magnet neodymium, anyị nwere ike ichebe ma gbasaa ndụ ọrụ nke magnet neodymium, ma kwalite ojiji ha n'ọtụtụ mpaghara.

Ⅰ.Ya mere, gịnị mere magnet neodymium ji efunahụ magnetism ha?

Otu ihe nwere ike ịkpata ya bụ mmetụta nke ike ndọta mpụga.

Mgbe magnet neodymium dị ike n'ime ike ndọta mpụga, njikọ magnet nwere ike ime, nke na-ebute ọnwụ nke magnetism ya. Na mgbakwunye, oke okpomọkụ nwekwara ike ibute mfu magnet neodymium, n'ihi na oke okpomọkụ ga-emebi nhazi nke mpaghara magnet dị n'ime ya.

Ihe ọzọ kpatara ya bụ mmebi kemịkalụ na oxidation nke magnet neodymium.

N'ịbụ ndị na-ekpughere gburugburu ebe mmiri dị ogologo oge, magnet neodymium nwere ike ịnweta mmeghachi omume oxidation, nke na-ebute ọdịdị nke oyi akwa oxide n'elu, nke ga-emetụta ihe onwunwe magnet ya.

Na mgbakwunye, mgbanwe mpaghara, hysteresis na ihe ndị mere agadi nwekwara ike ibute ọrịaobere magnet diski neodymiumiji tụfuo ndọta ha. Mgbanwe nke ngalaba ndọta na-ezo aka na nhazigharị nke ngalaba ndọta, nke na-ebute mbelata na njirimara ndọta. Hysteresis na-ezo aka na ndọta fọdụrụ nke magnet neodymium n'okpuru ọrụ nke ubi ndọta mpụga, ebe ịka nká na-ezo aka na mbelata nwayọ nke magnetism ka oge na-aga.

Ⅱ. Otu esi egbochi ma ọ bụ belata mfu nke magnetism nke Neodymium

A. Gburugburu ebe obibi na njikwa okpomọkụ dị mma

1. Usoro mgbochi n'ebe okpomọkụ dị elu

2. Ụzọ mbelata maka ịma jijiji na mmetụta

3. Usoro nchekwa megide ìhè na radieshon

B. Igbochi mmebi kemịkalụ na oxidation

1. A ga-ahọrọ ihe mkpuchi kwesịrị ekwesị

2. Mkpa ọ dị iji usoro mgbochi mmiri na uzuzu

C. Mee ka magnet Neodymium dị ogologo ndụ ọrụ

1. Mepụta usoro magnetik na sistemụ elektrọnik nke ọma

2. Nlekọta na nyocha mgbe niile

Ⅲ. Nlekọta na ojiji nke magnet neodymium.

Ihe ndị a bụ iji mee ka ọ pụta ìhè mkpa ọ dị ilekọta na iji ihe ndị a:

1. Ogologo ndụ ọrụ: Ụzọ mmezi na ojiji ziri ezi nwere ike ịgbatị ndụ ọrụ nke magnet neodymium. Dịka ọmụmaatụ, zere ikpughe na oke okpomọkụ ma ọ bụ iru mmiri, ma na-ehicha ma na-edozi ya mgbe niile.

2. Njirimara magnetik e ji n'aka: Ụzọ mmezi ziri ezi nwere ike ịnọgide na-enwe njirimara magnetik nke magnet neodymium. Nnyocha mgbe niile na izere ikpughe na ubi magnetik siri ike nwere ike igbochi mgbanwe mpaghara magnetik na ike ọgwụgwụ magnet.

3. Meziwanye nchekwa: Ụzọ e si eji ya nke ọma nwere ike imeziwanye nchekwa nke magnet neodymium. Izere nnukwu ihe mberede igwe na mgbanwe ogologo oge nke magnet cyclic nwere ike igbochi hysteresis na mfu nke magnetism, si otú a belata ihe egwu ndị nwere ike ime.

4. Chebe akụrụngwa dị n'akụkụ: Ụzọ e si eji ya nke ọma nwere ike ichebe akụrụngwa dị n'akụkụ. Kpachara anya ka ị ghara itinye magnet neodymium n'ebe ngwaọrụ eletrọnịkị dị nro nọ iji zere nnyonye anya na mmebi nke ngwaọrụ ndị ọzọ.

5. Nọgide na-arụ ọrụ n'ozuzu ya: Ụzọ mmezi ziri ezi nwere ike ime ka magnet neodymium rụọ ọrụ nke ọma. Nnyocha na nhicha magnet neodymium mgbe niile nwere ike iwepụ uzuzu, unyi, wdg, ma mee ka arụmọrụ ha sie ike.

Na nkenke, mfu nke magnetism nke neodymium magnet bụ nsogbu nke a ga-elebara anya ma dozie. Site n'ịghọta ihe kpatara ya na ime ihe ndị kwekọrọ na ya, anyị nwere ike ichebe ma mee ka magnet neodymium dị ogologo ma mee ka ọrụ ha dịkwuo ogologo ma hụ na ejiri ha mee ihe n'ọtụtụ ebe.

Ọ bụrụ na ị na-achọihe ndọta neodymium diski,neodymium iron boron magnet pụrụ iche, ị nwere ike ịhọrọ ụlọ ọrụ anyị Fullzen.
