Into yokuba Faraday evalelwe

Emva ngo-1836, isazinzulu waseBritani Maykl Faradey simnandi kakhulu kwaye ulwazi. Ngokutsho imiyalelo yakhe, Nentolongo lamaplanga zazityatyekwa amaphepha tin (alumuniyam eliqinileyo). Kwathiwa ke zodwa ukusuka kumphezulu womhlaba waza umthetho kusetyenziswa umatshini yombane. A umahluko okunokwenzeka yale uyilo kunye umhlaba namandla kangangokuba osondela imizimba edibene kumphezulu womhlaba iintolo zalo etshisayo kumphezulu yangaphandle. Ngoko ayimangalisi into yokuba Faraday ebuhlanti amangqina amaninzi eyoyikekayo. Sam IsiNgesi yemvelo yaba phakathi nesakhiwo sayo, ephethe electroscope ethe kakhulu.

Ukuba bavunyelwe ukuba bafumane Faraday yokuhlala?

Ngexesha test, neyunithi ziyalungiswa ngokupheleleyo ezandleni physics wabonisa ukungabi kwentlawulo zombane. Oku kuthetha ukuba isakhiwo efanayo zingasetyenziswa ngempumelelo nje yokuvalela njengekhaka. Kamva safumanisa ukuba isakhono umntu onjalo iskrini lwaze radiation magnetic kuxhomekeke Ebubanzini zayo ezibonakalayo, ubunzulu isiphumo komhlaba kunye umlinganiselo imingxunyana silinganiswa nobude amanyathelo otshangatshangiswayo. Ngenxa yoko, amalinge Faraday wakhokelela abantu bafumane indlela ukukhusela izixhobo ezibuthathaka kunye nempilo yabantu kwimiphumo eziyingozi enamandla intsimi electromagnetic. Lo mhlaba liye lasetyenziswa ngokubanzi xa befundisa, yaye kunzima ukucinga oko kuza kwenzeka uluntu ukuba kungekhona ngenxa bubulumko nesibindi nokwakheka onesibindi.

wenza njani Faraday yokuhlala?

Xa ivaliwe esingxotyeni conductive engena intsimi yombane, iqala kuchaphazela elektroni simahla, nto leyo ephambana iintlawulo uyilo bafumane enjalo, ukudala intsimi leyo ngokupheleleyo ukubuyekeza igalelo lwangaphandle. Kufuneka kuqatshelwe ukuba Faraday cage angakwazi ukukhusela kuphela intsimi yombane. A Imagnethi yomhlaba, ngokuxhomekeka ukuba emile, lihlaba ngokukhululekileyo. Ngoko ke, phakathi kongqameko le yoyilo iza kusebenza ngendlela eyiyo. Kwimeko intsimi olutshintshayo zombane nto elandelayo eyenzekayo: oko kudala yintsimi enamandla zibuthe, othe imithetho physics, ovelisa mtsalane yayo zombane, ukuthintela ukudaleka mhlaba otsalayo ngaphakathi yeskrini.

Modern Faraday yokuhlala

Okwangoku, vula IsiNgesi yamachiza nesenzeko zisetyenziselwa ezingontsini RF, igumbi zihlolwa, iibhokisi RF. izakhiwo ezinjalo ezisetyenziswa naphi na apho kuyimfuneko ukukhusela umntu evela entsimini yombane. Njengoko izinto zombane conductive ngoku ngokuqhelekileyo kusetyenziswa umnatha metal entle okanye amaxwebhu zentsimbi tubing, kunye nesakhiwo ngokwayo ngokuyimfuneko nisekelwe uthothe naziphi kwemisinga ombane ukuze kwimitha yangaphandle kuvuka.
Ukongeza, ebuhlanti Faraday isetyenziswa ngokubanzi kuzo zonke iintlobo zovavanyo izixhobo zekhompyutha, amacandelo ngekhompyutha njalo njalo. D. Kukho bade izixhobo zokuhlola umntu okhethekileyo, yaye ezinye iinkampani zinika ezindlini zabo ukuze ukuhluza abantu yokhuseleko ngcono.
