Kuj hu ua neo magnet, neodymium magnet yog ib hom hlau nplaum tsis tshua muaj neeg uas muaj neodymium, hlau thiab boron. Txawm hais tias muaj lwm yam hlau nplaum tsis tshua muaj neeg - suav nrog samarium cobalt - neodymium yog qhov feem ntau. Lawv tsim lub zog sib nqus muaj zog dua, ua rau muaj kev ua tau zoo dua. Txawm tias koj tau hnov txog neodymium magnets, tej zaum yuav muaj qee yam uas koj tsis paub txog cov hlau nplaum tsis tshua muaj neeg nrov no.
✧ Txheej txheem cej luam ntawm Neodymium Magnets
Cov hlau nplaum neodymium, uas yog lub ntiaj teb lub hlau nplaum ruaj khov tshaj plaws, yog cov hlau nplaum ua los ntawm neodymium. Yuav kom nkag siab txog lawv lub zog, lawv tuaj yeem tsim cov teb hlau nplaum nrog txog li 1.4 teslas. Neodymium, tau kawg, yog ib qho khoom tsis tshua muaj neeg paub uas muaj tus lej atomic 60. Nws tau tshawb pom hauv xyoo 1885 los ntawm tus kws tshuaj Carl Auer von Welsbach. Txawm hais li ntawd los, nws tsis yog txog li ib puas xyoo tom qab kom txog thaum cov hlau nplaum neodymium tau tsim.
Lub zog tsis muaj qhov sib piv ntawm cov hlau nplaum neodymium ua rau lawv yog qhov kev xaiv zoo rau ntau yam kev siv lag luam, qee qhov suav nrog cov hauv qab no:
Cov hard disk drives (HDDs) rau cov khoos phis tawj
ㆍXauv qhov rooj
ㆍCov cav tsheb fais fab
ㆍCov tshuab hluav taws xob
ㆍCov kauj suab
Cov cuab yeej hluav taws xob tsis muaj xov hlau
ㆍLub kauj tsheb fais fab
ㆍCov neeg hais lus thiab lub mloog pob ntseg
Cov khoom lag luam decouplers

✧ Keeb Kwm ntawm Neodymium Magnets
Cov hlau nplaum neodymium tau tsim nyob rau xyoo 1980s thaum ntxov. Cov tuam txhab tau pom tias los ntawm kev sib xyaw neodymium nrog me ntsis hlau thiab boron, lawv muaj peev xwm tsim cov hlau nplaum muaj zog. General Motors thiab Sumitomo Special Metals tom qab ntawd tau tso tawm cov hlau nplaum neodymium thawj zaug hauv ntiaj teb, muab lwm txoj hauv kev pheej yig dua li lwm cov hlau nplaum tsis tshua muaj nyob hauv khw.
✧ Neodymium VS Ceramic Magnets
Cov hlau nplaum neodymium piv rau cov hlau nplaum ceramic li cas? Cov hlau nplaum ceramic pheej yig dua, ua rau lawv yog qhov kev xaiv nrov rau cov neeg siv khoom. Txawm li cas los xij, rau cov ntawv thov lag luam, tsis muaj qhov hloov pauv rau cov hlau nplaum neodymium. Raws li tau hais ua ntej, cov hlau nplaum neodymium tuaj yeem tsim cov teb sib nqus nrog txog li 1.4 teslas. Piv txwv li, cov hlau nplaum ceramic feem ntau tsim cov teb sib nqus nrog tsuas yog 0.5 txog 1 teslas.
Tsis yog tsuas yog cov hlau nplaum neodymium muaj zog dua li cov hlau nplaum ceramic xwb; lawv kuj nyuaj dua thiab. Cov hlau nplaum ceramic yooj yim tawg, ua rau lawv yooj yim puas tsuaj. Yog tias koj poob cov hlau nplaum ceramic rau hauv av, muaj feem ntau nws yuav tawg. Cov hlau nplaum neodymium, ntawm qhov tod tes, yog cov khoom siv tawv dua, yog li lawv yuav tsis tawg thaum poob lossis raug kev ntxhov siab.
Ntawm qhov tod tes, cov hlau nplaum ceramic tiv taus xeb ntau dua li cov hlau nplaum neodymium. Txawm tias thaum raug dej noo tas li, cov hlau nplaum ceramic feem ntau yuav tsis xeb lossis xeb.
