Lub fact tias ib tug Faraday tawb

Rov qab nyob rau hauv 1836 ib tug British paub txog Maykl Faradey muaj ib tug heev nthuav thiab tuav kev. Raws li nws cov lus qhia, ib tug loj ntoo tawb plastered nrog los xij ntawm tin daim ntawv (ntawv ci). Nws twb ces cais los ntawm lub ntiaj teb nto thiab mas them siv cov hluav taws xob tshuab. Ib tug tej zaum txawv ntawm no tsim nrog rau hauv pem yog li ntawd muaj zog hais tias nws txuas rau hauv lub cev kev cob cog rua nrog lub ntiaj teb nto nrog nws txheej nto ya sparks. Nws yog tsis xav tsis thoob hais tias tus Faraday tawb Muaj ntau tus tim khawv awe-inspiring. Sam English physicist yog nyob rau hauv nws cov qauv, tuav ib tug heev rhiab electroscope.

Uas tau tso cai mus nrhiav Faraday tawb?

Thaum lub sij hawm lub xeem, lub tsev yog tag nrho serviceable nyob rau hauv lub ob txhais tes ntawm physics pom qhov tiav tsis tuaj kawm ntawv ntawm hluav taws xob xwb. Qhov no txhais tau tias ib tug zoo sib xws qauv yuav zoo siv raws li ib tug ntaub thaiv npog muab. Tom qab ntawd peb pom tawm hais tias lub peev xwm ntawm xws li ib tug kev tshuaj ntsuam rau neutralizing electromagnetic tawg nyob rau hauv lub thickness ntawm nws cov khoom, ntawm qhov tob ntawm qhov chaw nyhuv thiab tus piv ntawm keeb tsuas rau qhov ntev ntawm yoj kev txiav txim. Yog li, Faraday lub thwmsim coj neeg mus nrhiav ib txoj kev los tiv thaiv rhiab cov khoom thiab cov neeg kho mob los ntawm qhov teeb meem los ntawm ib tug haib electromagnetic teb. Qhov no tej khoom vaj tse tau lug siv nyob rau hauv kev xyaum, thiab nws yog ib qhov nyuaj rau xav txog tej yam dab tsi yuav tshwm sim los rau noob neej hais tias tsis rau lub ingenuity thiab siab tawv ntawm lub siab tawv physics.

Yuav ua li cas puas Faraday tawb?

Thaum kaw conductive sheath nkag mus rau hauv hluav taws xob field, nws pib mus rau cov dawb electrons, uas ua rau opposite qhia xws tsim tau nqi, tsim nyob rau hauv lem ib daim teb kiag compensating lwm yam. Nws yuav tsum tau muab sau tseg hais tias Faraday tawb yuav tiv thaiv tau xwb lub electric teb. Ib tug sib nqus teb, muab hais tias nws yog zoo li qub, dawb do penetrates. Yog li ntawd, nyob rau hauv lub compass ntawm no tsim yuav ua hauj lwm zoo. Nyob rau hauv cov ntaub ntawv ntawm lub dynamic hluav taws xob field ntawm lub tom ntej no tshwm sim: nws tsim ib dynamic magnetic teb, uas raws li cov kev cai ntawm physics, generates nws ua hluav taws xob teb, tiv thaiv cov creation ntawm ib tug sib nqus teb hauv lub screen.

Niaj hnub nimno Faraday tawb

Tam sim no, qhib English physicist phenomenon yog siv rau RF cabins, kuaj chav tsev, RF thawv. Tej thaj chaw lug siv peb txog qhov twg tsim nyog los tiv thaiv tus txiv neej los ntawm cov hluav taws xob field. Raws li cov electrically conductive khoom yog tam sim no feem ntau siv zoo hlau mesh los yog perforated steel los xij, thiab cov qauv nws tus kheej tas grounded dissipate tej hluav taws xob currents uas tej zaum yuav tshwm sim los ntawm lwm tawg.
Nyob rau hauv tas li ntawd, lub Faraday tawb yog dav siv rau tag nrho cov hom ntawm cov kev ntsuam xyuas ntawm lub computer cov khoom, hluav taws xob Cheebtsam thiab thiaj li nyob. D. Muaj txawm tshwj xeeb ib tug neeg kuaj khoom siv, thiab ib co tuam txhab uas muag muab lawv qhov los soj ntsuam cov neeg zoo ruaj ntseg.
