Loj Neodymium Disc Magnets – Kev daws teeb meem | Fullzen

Qhov loj tshaj plaws neodymium hlau nplaum tam sim no muaj nyob rau hauv kev lag luam feem ntau yog nyob rau hauv daim ntawv ntawm ib tug thaiv los yog disc hlau nplaum, nrog rau qhov ntev ntawm ob peb nti mus rau ob peb nti nyob rau hauv ntev thiab dav. Cov hlau nplaum neodymium loj dua no tuaj yeem muaj cov hlau nplaum sib nqus tseem ceeb thiab siv rau hauv ntau yam kev siv xws li cov cuab yeej siv, sib nqus sib nqus, lub cev muaj zog, thiab cov tshuab hluav taws xob.Thaum tsis muaj qhov loj me me rau cov hlau nplaum neodymium, nws tseem ceeb heev uas yuav tsum nco ntsoov tias raws li qhov loj me, cov hlau nplaum hlau nplaum yuav txo qis. Qhov no yog vim cov hlau nplaum loj dua tuaj yeem muaj peev xwm ntau dua ntawm cov khoom sib nqus sab hauv uas tshem tawm ib leeg tawm, txo lawv lub zog tag nrho cov hlau nplaum. Txawm li cas los xij, kev nce qib hauv kev tsim cov hlau nplaum tau tso cai rau kev tsim cov hlau nplaum neodymium loj dua nrog cov khoom sib nqus zoo dua.

Neodymium disc hlau nplaum, tseem hu ua neodymium round hlau nplaum lossis neodymium cylinder hlau nplaum, yog cov hlau nplaum me me uas ua los ntawm neodymium-iron-boron (NdFeB) alloy. Lawv yog cov hlau nplaum ruaj khov uas muaj zog tshaj plaws nyob rau hauv kev lag luam.Cov hlau nplaum no feem ntau ua nyob rau hauv ib daim duab disc, qhov twg txoj kab uas hla yog siab tshaj qhov siab (thickness), uas ua rau lub tiaj tiaj. Lawv tuaj nyob rau hauv ntau qhov ntau thiab tsawg, nrog cov diameters thiab thicknesses xws li ob peb millimeters mus rau ob peb nti.Vim lawv lub zog sib nqus, neodymium disc hlau nplaum tau siv dav hauv ntau yam kev siv, nrog rau cov khoom siv hluav taws xob, cov khoom siv kho mob, kev lag luam tsheb, khoom siv tes ua thiab kev nyiam ua haujlwm, sib nqus kaw, cov hniav nyiaj hniav kub sib nqus, thiab txawm nyob rau hauv kev sib nqus levitation thwmsim. Muab lawv qhov me me thiab muaj zog sib nqus, lawv yuav tsum tau ceev faj vim lawv tuaj yeem nyiam lossis tawm tsam lwm yam khoom sib nqus thiab tuaj yeem ua rau raug mob yog tias tsis raug.

Tus "N" hauv neodymium txhais tau tias yog lub cim tshuaj lom neeg ntawm cov khoom neodymium nws tus kheej. Neodymium (Nd) yog ib qho khoom tsis tshua muaj neeg nyob hauv lanthanide series ntawm lub rooj periodic. Nws tau muab lub npe los ntawm cov lus Greek "neos" txhais tau tias "tshiab" thiab "didymos" txhais tau tias "ntxaib," uas qhia txog nws qhov kev tshawb pom ua ib qho khoom ntxaib rau cov khoom uas tau paub yav dhau los, praseodymium. Neodymium yog siv dav hauv kev tsim cov hlau nplaum ruaj khov, zoo li cov hlau nplaum neodymium, vim nws cov khoom sib nqus siab. Cov khoom no pab txhawb rau lub zog sib nqus uas pom los ntawm cov hlau nplaum neodymium, ua rau lawv nrhiav tau hauv ntau yam kev siv uas xav tau lub zog sib nqus muaj zog.
