Faraday cage
Faraday cagen. A container made of a conductor, such as wire mesh or the metal frame of an aircraft, forming an equipotential shield around what it encloses and protecting it from external electric fields. Also called Faraday shield.
[After Michael Faraday, who constructed one in 1836.]Faraday cage n (Electronics) an earthed conducting cage or container used to protect electrical equipment against electric fields [C20: named after Michael Faraday]TranslationsFaraday cage
Faraday cage[′far·ə‚dā ‚kāj] (electricity) Faraday shield Faraday cageA shielded enclosure used to block electric fields from reaching its content. Constructed of metal, the cage conducts current on its exterior but prevents it from reaching inside. The Faraday cage was invented by physicist Michael Faraday in 1836.
Home-made cages are made by wrapping a cardboard box with aluminum foil or using metal garbage cans or anti-static bags. Items placed inside can also be wrapped with layers of aluminum foil. See EMP and Farad.Faraday cage
Faraday cage A hollow metal cylinder used to detect ions in mass spectrometry. Ions enter the open end and impact either on the metal walls or the closed end. Each singly charged ion carries a charge of 1.6 x 1019 coulombs; the summed ion current carried by the ions is measured directly.Faraday, Michael, English physicist and chemist, 1791-1867. farad - a practical unit of electrical capacity.faraday - 96,485.309 coulombs per mole, the amount of electricity required to reduce one equivalent of silver ion.Faraday cage - cage designed to enclose and protect an electric instrument from outside electric interference.Faraday constantFaraday laws - the amount of an electrolyte decomposed by an electric current is proportional to the amount of the current.faradic bath - water bath in which there is faradic current.faradic current - current that stimulates muscle through its nerve.faradism - Synonym(s): faradizationfaradization - use of the faradic current.
