yuav ua li cas tiv thaiv magnetic teb

Sib nqus teb yog nyob ib ncig ntawm peb, los ntawm lub ntiaj teb nws tus kheej mus rau cov khoom uas peb siv txhua hnub. Txawm li cas los xij, lub zog ntawm cov teb no tuaj yeem sib txawv heev thiab tuaj yeem ua rau muaj kev phom sij rau kev noj qab haus huv thiab kev nyab xeeb yog tias tsis tswj xyuas kom zoo.

Thawj kauj ruam ntawm kev tiv thaiv cov hlau nplaum yog nkag siab txog lub zog thiab zaus ntawm daim teb. Qhov no tuaj yeem ua tau los ntawm kev ntsuas lub teb nrog cov cuab yeej xws li gaussmeter lossis magnetometer. Nws tseem yog ib qho tseem ceeb kom paub txog txhua qhov chaw ntawm cov hlau nplaum hauv koj ib puag ncig, xws li cov kab hluav taws xob lossis cov khoom siv hluav taws xob.

Thaum lub zog thiab zaus ntawm cov magnetic teb tau nkag siab, cov kauj ruam tuaj yeem ua kom txo tau qhov raug. Qhov no tuaj yeem suav nrog kev tiv thaiv thaj chaw nrog cov khoom siv hlau nplaum, xws li mu-hlau lossis permalloy. Cov ntaub ntawv no yog tsim los hloov lossis nqus cov chaw sib nqus, txo qhov raug tag nrho.

Lwm qhov kev xaiv rau kev tiv thaiv cov hlau nplaum yog siv cov cuab yeej tiv thaiv tus kheej, xws li cov khaub ncaws tiv thaiv sib nqus lossis cov khoom siv ntxiv. Cov khoom no yog tsim los thaiv lossis txo qhov raug cov chaw sib nqus, ua kom tus neeg hnav kom tsis txhob muaj kev pheej hmoo rau kev noj qab haus huv.

Tsis tas li ntawd, nws yog ib qho tseem ceeb uas yuav tsum ua raws li cov txheej txheem kev nyab xeeb thiab cov lus qhia thaum ua haujlwm ze ntawm cov hlau nplaum muaj zog, xws li cov uas pom hauv MRI cov cav tov lossis cov cuab yeej siv. Qhov no suav nrog kev hnav cov iav tiv thaiv tsim nyog thiab xyuas kom tsis muaj cov khoom siv hlau nyob hauv cheeb tsam.
