Kev ua tau zoo ntawm cov hlau nplaum neodymium yuav txawv nyob ntawm cov khoom siv hlau nplaum, qib, thiab lwm yam.
Cov hlau nplaum qib qhia qhov zoo lossis purity ntawm cov khoom siv los tsim cov hlau nplaum. Yog tias tag nrho lwm yam sib npaug, cov hlau nplaum uas muaj qib siab dua yuav muaj zog dua. Cov hlau nplaum qib tau teev tseg raws li nws yog tus lej "N". Cov qib ntau tshaj plaws rau cov hlau nplaum neodymium yog N35, N38, N40, N42, N48, N50, N52, thiab N55.
Gauss ntsuam xyuas ntawm neodymium hlau nplaum txiav txim siab npaum li cas cov hlau nplaum ua haujlwm. Qhov no yuav raug hu ua magnetic induction lossis magnetic flux density, thiab qee zaum nws tau sawv cev los ntawm lub cim G lossis Gs. Gauss system ntawm kev ntsuas, uas yog tseem siv nyob rau hauv magnetism, feem ntau tau supplanted los ntawm lub International System of Units (SI), ces koj yuav pom Gauss ntsuam xyuas qhia nyob rau hauv SI es tsis yog Gs. SI unit rau magnetic flux density yog Tesla (T), uas sib npaug 10, 000 gauss.
Ntxiv nrog rau qib thiab sib nqus flux ceev, ib qho hlau nplaum qhov kev ua tau zoo yuav cuam tshuam los ntawm nws cov duab thiab tuab. Feem ntau, nrog rau tag nrho lwm yam sib npaug, cov hlau nplaum loj yuav tsim muaj zog rub ntau dua li cov hlau nplaum me.
Ib puag ncig kub thiab qhov sib thooj rau lwm yam khoom siv hlau nplaum kuj tuaj yeem cuam tshuam kev ua haujlwm ntawm cov hlau nplaum. Cov ntawv thov kub thiab sib tw sib nqus sib nqus tuaj yeem txo qhov kev ua haujlwm ntawm cov hlau nplaum neodymium lossis txawm tias de-magnetize lawv, yog li nws tseem ceeb kom nkag siab tias cov hlau nplaum yuav siv li cas thaum xaiv cov hlau nplaum zoo rau txoj haujlwm.
