Da hujjar cewa Faraday keji

Back a 1836 a Birtaniya masanin kimiyya Maykl Faradey yana da matukar ban sha'awa da kuma m gwaninta. Bisa ga umarnin, a manyan katako shafe tare da zanen gado na tin takarda (tsare). An sa'an nan ware daga duniya ta surface da kuma sosai cajin amfani da lantarki na'ura. A m bambanci da wannan zane da ƙasa ya da karfi da cewa ya fuskanci gawawwakin da alaka da duniya ta surface tare da matsanancin surface Flying tartsatsi. Ba abin mamaki ba cewa Faraday keji da yawa shaidu masu ban tsoro. Sam Turanci likita ya cikin tsarinta, rike da wani sosai m electroscope.

Wannan yarda a sami Faraday keji?

A lokacin gwajin, naúrar ne Mafi serviceable a hannun kimiyyar lissafi ya nuna cikakken babu lantarki cajin.

Ta yaya Faraday keji?

Lokacin da rufe conductive daina kai hare hare ta shiga lantarki filin, sai ta fara shafar free electrons, sakamakon gaban kwatance irin zane acquire zargin, samar da bi da bi a filin gaba daya compensating waje tasiri. Ya kamata a lura cewa Faraday keji iya kare kawai lantarki filin. A halin maganaɗisu filin, da sharadin cewa shi ne a tsaye, da yardar kaina shiga. Saboda haka, a cikin kamfas na wannan zane za ta yi aiki daidai. A cikin hali na tsauri lantarki filin na gaba abu ya faru: Halicci tsauri Magnetic filin, wanda bisa ga dokokin kimiyyar lissafi, ya haifar da sãɓãwar launukansa lantarki filayen, hana halittar wani Magnetic filin ciki na allo.

Modern Faraday keji

A halin yanzu, bude Turanci likita sabon abu da ake amfani da RF bukkokin, kariya dakin, RF kwalaye. Irin wannan gabatarwa an yadu amfani duk inda wajibi ne don kare mutum daga lantarki filin. Kamar yadda electrically conductive abu ne yanzu amfani lafiya karfe raga ko perforated karfe zanen gado, da kuma tsarin da kanta dole na rasa zuwa dissipate wani lantarki igiyoyin da zai bayyana daga waje radiation.
Bugu da kari, da Faraday keji ne yadu amfani ga kowane irin gwaje-gwaje na kwamfuta kayan aiki, lantarki da sauransu. D. Akwai ma na musamman mutum nunawa kaya, da kuma wasu kamfanonin bayar da Apartments su duduba mutane ga mafi alhẽri tsaro.
