Raws li ib qho khoom tsim muaj, NdFeB hlau nplaum tau nyob rau lub lag luam rau ib lub sijhawm ntev. Txij li thaum xyoo 1982, lawv tau siv ntau ntau heev nyob rau ntau lub teb, thiab tau muab piv rau cov khoom sib thooj hauv tib lub ntim. Sib zog nqus cov teebmeem ntau dua vim nws yog siv rau ntau yam ntxiv. Raws li kev lag luam hloov kho rau kev lag luam, tus nqi ntawm cov hlau nplaum Nd-Fe-B tau nyob ntawm tus nqi ruaj. Ntev ntev npaum li cas ntawm Nd-Fe-B hlau nplaum tsis loj heev, dab tsi ua rau qhov no? ? Nws yog ib qho zoo!
Zoo yog qhov laj thawj tsim nyog vim li cas cov khoom tsim tawm thiab muag. Qhov no kuj muaj nyob rau hauv cov ntaub ntawv NdFeB. Tus nqi siab ntawm NdFeB hauv txoj kev vam meej yog tsim los ntawm cov khoom me me hauv lub khw. Lub sij hawm ntawd, ntau tus neeg xav tau nce tus nqi kom tau cov khoom siv sib nqus no, tiam sis ua rau cov khoom tseem tuaj yeem nthuav dav ntxiv, cov nqi ntawm cov khoom zuj zus ntxiv, tom qab lub khw muag khoom noj thiab kev lag luam hauv lub khw, qhov tseem ceeb tshaj plaws uas tuaj yeem cuam tshuam qhov nqi yog zoo.
Txawm hais tias lub ntim ntau lawm ntau zog, qhov zoo ntawm NdFeB nkag los ntawm cov tuam txhab txawv tsis zoo ib yam. Seb nws yog vim muaj qhov sib txawv hauv cov khoom siv los yog vim muaj teeb meem ntawm cov neeg ua haujlwm cov neeg ua haujlwm, nws tau coj mus nkag ntawm NdFeB cov hlau nplaum sib txawv hauv cov khw. Yuav muaj kev sib piv. Lawm, zoo zoo yog luv luv. Vim muaj teeb meem dab tsi, tus nqi yuav yog me ntsis siab dua. Ntawm qhov tod tes, tsis muaj ntau cov ntaub ntawv uas cov hlau nplaum neodymium-hlau-boron yuav tsum muaj cov ntaub ntawv zoo. Qee cov khoom siv kuj tsis tshua zoo rau cov hlau nplaum neodymium-hlau-boron, uas ua rau nyias qhov txawv ntawm NdFeB. Sib txawv cov nqi ces nyob hauv ntau lub lag luam phenomena.
