Faraday cage

[fer′ədā]
a wire-mesh cage that surrounds a magnetic resonance (MR) scanner and shields it from stray radiofrequency waves. Such waves would otherwise distort the results of MR imaging.

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.

Faraday cage - cage designed to enclose and protect an electric instrument from outside electric interference.
Faraday constant
Faraday laws - the amount of an electrolyte decomposed by an electric current is proportional to the amount of the current.
