Xaqiiqada ah in qafis Faraday a

Back ee 1836 saynisyahan British ah Maykl Faradey lahaa khibrad aad u xiiso badan oo wargelin ah. Sida laga soo xigtay tilmaamaha uu, a qafis alwaax waaweyn malaasay iyadoo la adeegsanayo waraaqaha of warqad daasadda (bireed). haddana waxaa la go'doonsan lagana rujiyey dhulka iyo sare eedeeyay isticmaalayo mashiinka korontada. Farqiga A iman kara of design this dhulka la ahaa si xoog leh in ay gabogabo tahay meydadka xiran dusha dhulka ee dusha dibadda dhimbiiluhu ay duulaya. Ma aha la yaab leh in qafis Faraday Marag badan oo ka Yaabid-dhiirigalin leh. jirka Sam Ingiriisi ku dhex jiray ay qaab-dhismeedka, haysta electroscope aad u xasaasi ah.

In la ogol yahay in la helo qafis Faraday?

Waqtiga baaritaanka, unit si buuxda u shaqeyn in gacmaha physics tusay maqnaanshaha dhamaystiran oo lacag koronto. Taas macnaheedu waa in qaab la mid ah loo isticmaali karaa si waxtar leh sida lifaqaya gaashaan. Later waxaan ogaanay in awoodda ee shaashadda sida a for neutralizing shucaaca electromagnetic ku xiran tahay dhumucda ay wax, si qoto dheer ee saameynta dusha iyo ratio ee furan xajmi in dhererka tallaabo la ruxruxo. Sidaas darteed, tijaabo Faraday ee dadka keentay in la helo hab lagu qalabka xasaasi ah iyo caafimaadka dadka ka waxyeellada daran ee awood ilaaliyo beerta electromagnetic. hantida waxaa loo isticmaalo si dhab ah, oo way adag tahay in la qiyaaso waxa dhici lahaa Dadka haddii aanad ee xariif iyo geesinimada of physics geesiga.

Sidee qafis Faraday?

Marka xiran galkeeda tabinta galo beerta korontada, ay bilowdo inay saamayn ku electrons free, taasoo keentay in tilmaamaha soo horjeeda eedeeyay wareegi design sida, la abuuro oo iyana beer si buuxda ugu celino saamaynta dibadda. Waa in la ogaadaa in Faraday qafis ilaalin karaa oo keliya duurka oo korontada ah. beerta A magnetic, ay shardi tahay in uu yahay ma guurto ah, xor ah guskiisa. Sidaa darteed, gudahood ku wareegsan meesha of design this si sax ah u shaqeyn doono. In the case duurka firfircoon korontada waxa xiga ee dhici doona: waxay abuurtaa beer firfircoon magnetic, kaas oo sida uu qabo sharciga of physics, abuuraa kala duwan beeraheedii korontada, ka hortagga abuurka beer magnetic gudaha ee shaashadda.

Modern Faraday qafis

Waqtigan xaadirka ah, furan ifafaale jirka Ingiriisi waxa loo isticmaalaa weliba qolalkii hoose RF, qolka la baaray, sanduuqyada RF. dhismaha noocan oo kale ah waxaa loo meel kasta oo lagama maarmaan ah in laga duurka oo korontada ilaaliyo nin. Sida wax koronto tabinta ayaa hadda si caadi ah loo isticmaalo mesh biraha ganaax ama go'yaal steel dalool, iyo qaab-dhismeedka laftiisa qasab ku xeeldheer dhereggu kasta oo hadda korontada laga yaabaa in kac ka shucaaca dibedda ah.
Intaa waxaa dheer, qafis Faraday ah waxaa si balaadhan looga isticmaalaa dhammaan noocyada kala duwan ee imtixaanada qalab computer, qaybaha electronic iyo D. sidaas on. Waxaa jira xitaa xirmooyinka baaritaanka shaqsi gaar ah, iyo shirkadaha qaarkood waxay bixiyaan guryaha si ay u baaraan dadka ammaanka wanaagsan.
