twg hlau nplaum yog qhov muaj zog tshaj

Feem ntau, cov hlau nplaum neodymium tam sim no suav tias yog hom hlau nplaum muaj zog tshaj plaws.

Neodymium hlau nplaum, tseem hu ua NdFeB hlau nplaum, yog tsim los ntawm kev sib xyaw ntawm neodymium, hlau, thiab boron. Lawv tau tsim thawj zaug hauv xyoo 1980s thiab txij li ntawd los tau siv dav hauv ntau daim ntawv thov vim lawv cov khoom sib nqus zoo heev. Lub zog ntawm cov hlau nplaum neodymium yog ntsuas nyob rau hauv units ntawm magnetic flux ntom, hu ua Tesla (T).

Tam sim no, cov lag luam muaj zog tshaj plaws neodymium hlau nplaum muaj cov sib nqus flux ntom ntawm ib puag ncig 1.4 T. Cov ntaub ntawv ntau, suav nrog cov kev siv rau ntau, suav nrog cov tshuab raj, hluav taws xob, thiab hais lus. Tsis tas li ntawd, cov hlau nplaum neodymium yog cov resistant rau demagnetization thiab muaj lub neej ntev.

Tau kawg, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias lub zog ntawm cov hlau nplaum tsis yog tib qho uas yuav tsum tau xav txog thaum xaiv cov hlau nplaum zoo rau koj cov kev xav tau. Lwm yam, xws li qhov loj me, cov duab, thiab cov kev taw qhia magnetic teb, kuj tuaj yeem cuam tshuam cov hlau nplaum ua haujlwm hauv ib daim ntawv thov.
