yuav hlau nplaum ua haujlwm los ntawm iav

Hauv luv luv, cov lus teb yog yog, cov hlau nplaum yuav ua haujlwm los ntawm iav nyob ntawm qhov tuab ntawm iav. Lub zog ntawm cov hlau nplaum thiab qhov kev ncua deb ntawm cov hlau nplaum thiab cov iav yuav cuam tshuam nws cov kev ua tau zoo los ntawm cov iav.

Ib lub tswv yim tseem ceeb los xav txog yog cov eddy tam sim no nyob rau hauv cov hlau thiab cov khoom siv hluav taws xob, suav nrog iav. Cov no yog cov tam sim no uas circulate nyob rau hauv cov khoom thaum raug magnetic teb. Qhov tam sim no generates nws magnetic teb uas tawm tsam tus thawj magnetic teb, uas thaum kawg absorbs ib co ntawm cov qub magnetic zog. Lub iav thicker, qhov ntau dua qhov tsis kam thiab qhov tseem ceeb ntawm qhov attenuation.

Txawm li cas los xij, rau cov ntaub ntawv iav nyias, cov hlau nplaum tuaj yeem ua haujlwm tau zoo thiab ua kom pom qhov qis qis, ua tiav cov nyhuv electromagnetic ntawm qhov deb mus txog li ob peb centimeters deb ntawm lub iav nto. Hauv qhov sib piv, cov iav tuab tuaj yeem cuam tshuam kev sib nqus sib nqus, ua rau lub zog sib nqus tsis muaj zog thiab txo lub zog sib nqus.

Tsis tas li ntawd, hom hlau nplaum siv kuj ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab nws cov txiaj ntsig los ntawm iav. Cov hlau nplaum tas mus li, xws li cov hlau nplaum neodymium, yog qhov zoo tshaj plaws rau cov ntawv siv iav vim tias lawv cov hlau nplaum seem muaj zog. Cov hlau nplaum no tuaj yeem tuav rau ntawm cov iav nyias, tso saib rooj plaub, thiab tub yees, thiab lwm yam kev siv.
