Qhov sib txawv tseem ceeb ntawm neodymium thiab ferrite hlau nplaum yog cov hlau nplaum neodymium muaj neodymium, hlau thiab boron ua cov khoom tseem ceeb thaum cov hlau nplaum ferrite muaj hlau ua cov khoom tseem ceeb.
Cov hlau nplaum ntiaj teb tsis tshua muaj zog, cov hlau nplaum ruaj khov. Ferrite hlau nplaum tsis muaj zog npaum li ntawd. Cov hlau nplaum ceramic thiab cov hlau nplaum tsis tu ncua yog ob lub npe rau cov hlau nplaum ferrite.
Neodymium Magnets yog dab tsi?
Neodymium hlau nplaum yog ib hom hlau nplaum uas tsis tshua muaj hauv ntiaj teb uas muaj neodymium, hlau thiab boron. Muaj ob hom hlau nplaum uas tsis tshua muaj ntiaj teb. Ib qho yog neodymium hlau nplaum thiab lwm qhov yog samarium-cob alt hlau nplaum. Cov no yog cov hlau nplaum ruaj khov. Tsis tas li, cov hlau nplaum no muaj cov hlau nplaum ntawm cov hlau hais hauv daim ntawv ntawm Nd
2Fe14B tetragonal crystalline qauv. Tsis tas li ntawd, nws yog cov khoom lag luam qib hlau nplaum uas muaj zog tshaj plaws uas muaj tam sim no. Yog li, cov hlau nplaum no tuaj yeem hloov tau ntau hom hlau nplaum hauv cov khoom siv niaj hnub xws li lub cev muaj zog hauv cov cuab yeej cordless.
Daim duab 01: Neodymium Magnet Balls
Neodymium yog cov khoom siv ferromagnetic; yog li ntawd, peb tuaj yeem tsim nws los ua cov hlau nplaum. Txawm li cas los xij, Curie kub (cov khoom siv uas cov hlau nplaum poob nws cov hlau nplaum) ntawm cov khoom no tsawg heev. Yog li ntawd, nyob rau hauv nws daim ntawv ntshiab, nws qhia tau hais tias magnetism nyob rau hauv uas tsis tshua muaj kub. Tab sis, yog tias peb ua cov hlau nplaum ntawm neodymium nrog qee cov hlau hloov pauv xws li hlau, peb tuaj yeem txhim kho cov hlau nplaum ntawm cov khoom siv no. Daim ntawv txhim kho yog qhov peb hu ua "neodymium hlau nplaum".
Ferrite Magnets yog dab tsi?
Ferrite hlau nplaum yog cov khoom siv ceramic uas muaj cov khoom ferromagnetic. Yog li ntawd, peb hu lawv cov hlau nplaum ceramic. Cov hlau nplaum tsis tu ncua yog lwm lub npe rau cov hlau nplaum ferrite vim cov hlau nplaum no feem ntau yog siv rau lub hom phiaj tsis tu ncua. Qhov tseem ceeb ntawm cov hlau nplaum no yog ferrite. Ferrite yog cov khoom siv ceramic. Nws feem ntau muaj hlau (III) oxide. Peb muab cov khoom sib xyaw no nrog qee cov hlau xws li barium, manganese, nickel thiab zinc. Cov khoom no yog ferromagnetic thiab hluav taws xob uas tsis yog-conductive.
Daim duab 02: Nplhaib ntawm Ferrite Magnets
Tsis tas li ntawd, cov hlau nplaum no muaj qhov tsis zoo (lub zog ntawm cov hlau nplaum), coercivity (khoom siv los ua demagnetized) piv. Tab sis, muaj ob hom ferrite hlau nplaum li nyuaj ferrites thiab mos ferrites raws li coercivity (siab thiab qis feem). Sib nrug los ntawm qhov ntawd, cov khoom siv hluav taws xob (qhov ntom ntom ntawm lub zog sib nqus) kuj tsawg heev. Txawm li cas los xij, Curie kub yog qhov sib piv siab.
Qhov txawv ntawm Neodymium thiab Ferrite Magnets yog dab tsi?
Neodymium hlau nplaum yog ib hom hlau nplaum uas tsis tshua muaj hauv ntiaj teb uas muaj neodymium, hlau thiab boron thaum ferrite hlau nplaum yog cov khoom siv ceramic uas muaj cov khoom ferromagnetic. Yog li, qhov sib txawv tseem ceeb ntawm neodymium thiab ferrite hlau nplaum yog cov hlau nplaum neodymium muaj neodymium, hlau thiab boron raws li cov ntsiab lus tseem ceeb thaum ferrite hlau nplaum muaj hlau ua cov khoom tseem ceeb.
Ntxiv mus, cov hlau nplaum neodymium muaj qhov sib piv siab heev, coercivity thiab zog khoom thaum nyob rau hauv cov hlau nplaum ferrite, cov no tsawg heev. Tsis tas li ntawd, qhov sib txawv ntxiv ntawm neodymium thiab ferrite hlau nplaum yog qhov kub ntawm cov hlau nplaum neodymium tsawg heev tab sis nyob rau hauv cov hlau nplaum ferrite, nws yog siab heev.
Summary – Neodymium vs Ferrite Magnets
Neodymium hlau nplaum yog ib hom hlau nplaum uas tsis tshua muaj hauv ntiaj teb uas muaj neodymium, hlau thiab boron. Ferrite hlau nplaum yog cov khoom siv ceramic uas muaj cov khoom ferromagnetic. Qhov sib txawv tseem ceeb ntawm neodymium thiab ferrite hlau nplaum yog cov hlau nplaum neodymium muaj neodymium, hlau thiab boron raws li cov ntsiab lus tseem ceeb thaum cov hlau nplaum ferrite muaj hlau ua cov khoom tseem ceeb.
