yuav ua li cas magnetic teb ua haujlwm

Ib qho chaw sib nqus yog tsim los ntawm kev txav ntawm cov nqi hluav taws xob, tshwj xeeb yog qhov ntws ntawm electrons. Thaum cov electrons txav mus, lawv tsim ib qho chaw sib nqus nyob ib puag ncig lawv. Daim teb no tuaj yeem nyiam lossis tawm tsam lwm yam khoom sib nqus, nyob ntawm qhov kev taw qhia ntawm daim teb. Lub zog ntawm cov hlau nplaum yog ntsuas hauv gauss lossis tesla.

Hauv peb cov khoom, peb siv cov hlau nplaum los tsim cov hlau nplaum no. Cov hlau nplaum yog tsim los ntawm cov ntaub ntawv uas muaj kev sib nqus siab, txhais tau tias lawv muaj lub zog muaj zog los ua hlau nplaum. Thaum cov hlau nplaum raug rau ib qho chaw sib nqus, cov khoom siv hlau nplaum sib haum nrog lub teb, ua rau nws dhau los ua cov hlau nplaum nws tus kheej. Lub zog ntawm cov hlau nplaum yog txiav txim siab los ntawm cov khoom ntawm cov khoom siv hlau nplaum, xws li nws muaj pes tsawg leeg thiab qhov loj me.

Kev siv rau magnetic teb nyob rau hauv peb cov khoom yog loj heev. Los ntawm cov khoom sib nqus mus rau cov ntaub ntawv khaws cia, cov hlau nplaum ua lub luag haujlwm tseem ceeb hauv peb lub neej txhua hnub. Hauv kev kho mob, cov teb sib nqus tau siv hauv cov tshuab magnetic resonance imaging (MRI) los tsim cov duab ntxaws ntxaws ntawm lub cev sab hauv. Hauv kev lag luam automotive, magnetic teb yog siv nyob rau hauv sensors los ntes txoj hauj lwm thiab ceev, raws li zoo raws li nyob rau hauv alternators thiab starters los hloov txhua yam zog rau hauv hluav taws xob zog.

Txawm hais tias lawv siv ntau, cov hlau nplaum kuj tuaj yeem tsim kev puas tsuaj yog tias tsis siv kom raug. Cov hlau nplaum muaj zog tuaj yeem cuam tshuam nrog cov pacemakers, ua rau lawv ua haujlwm tsis zoo lossis kaw. Nws yog ib qho tseem ceeb kom muaj kev tiv thaiv kev nyab xeeb nyob rau hauv qhov chaw thaum ua hauj lwm nrog magnetic teb kom tsis txhob raug mob los yog puas tsuaj rau cov khoom.
