Saturation magnetization yog hais txog cov txheej txheem uas cov hlau nplaum ntawm cov khoom sib nqus mus txog lub xeev saturated nyob rau hauv qhov kev txiav txim ntawm sab nraud magnetic teb. Thaum lub sij hawm tus txheej txheem no, lub magnetization ntawm cov khoom sib nqus nce mus txog rau thaum nws mus txog nws qhov siab tshaj plaws tus nqi. Tus nqi siab tshaj no feem ntau hu ua saturation magnetization.
Saturation magnetization yog ib qho tseem ceeb ntawm lub cev tshwm sim thiab nws muaj kev siv dav hauv ntau qhov chaw. Piv txwv li, hauv cov khoom siv fais fab xws li motors, transformers, generators, etc., saturation magnetization yog ib qho tseem ceeb heev. Vim tias cov khoom siv no tsuas tuaj yeem ua haujlwm tau zoo nyob rau hauv saturation magnetization.
Ntxiv rau nws daim ntawv thov hauv cov khoom siv fais fab, saturation magnetization muaj ntau lwm yam kev siv. Piv txwv li, hauv computer nco, cov khoom sib nqus ntawm lub disk yuav tsum tau saturated thiab magnetized ua ntej nws tuaj yeem khaws cov ntaub ntawv. Tsis tas li ntawd, nyob rau hauv kev kho mob imaging technology, magnetic resonance imaging (MRI) siv saturation magnetization rau duab tib neeg lub cev.
Saturation magnetization muaj kev txiav txim siab ntawm kev ua haujlwm ntawm cov khoom sib nqus. Ntawm qhov tod tes, nws tuaj yeem txhim kho cov khoom sib nqus ntawm cov khoom sib nqus thiab txhim kho lawv cov hlau nplaum, sib nqus permeability thiab lwm yam ntawm lub cev; ntawm qhov tod tes, nws kuj tseem tuaj yeem hloov cov khoom sib nqus ntawm cov khoom sib nqus kom lawv muaj cov khoom sib nqus tshwj xeeb, xws li kev sib nqus nco, sib nqus permeability, thiab lwm yam. Resistance thiab lwm yam.
Vim li cas cov hlau nplaum tsis tuaj yeem ncav cuag saturation magnetization? Muaj cov laj thawj hauv qab no.
Ua ntej, cov khoom txwv. Cov ntaub ntawv sib txawv muaj qhov sib txawv hauv ib puag ncig hauv hluav taws xob, ua rau lub sijhawm sib nqus sib nqus sib txawv. Qee cov ntaub ntawv tsis tuaj yeem ua tiav cov hlau nplaum sib nqus txawm tias lawv tau txais cov hlau nplaum muaj zog heev.
Qhov thib ob, muaj kev txwv rau qhov chaw sib nqus. Txawm hais tias sab nraud magnetic teb muaj zog magnetizing muaj peev xwm, yog tias nws qhov loj me tsis txaus, saturation magnetization tsis tuaj yeem ua tiav. Tshwj xeeb tshaj yog muaj zog sib nqus cov ntaub ntawv xav tau ib tug muaj zog magnetic teb los magnetize lawv mus saturation.
