Faraday noun. In sense 2 faraday. M19.
[Michael Faraday (1791-1867), English scientist.]
Physics & Chemistry.
I.
Used attrib. and in possess. to designate things discovered, invented, or explained by Faraday. M19.
Faraday cage an earthed metal screen surrounding a piece of equipment to protect it from external electrostatic interference. Faraday constant = sense 2 below. Faraday dark space: see Faraday's dark space below. Faraday effect the rotation of the plane of polarization of electro-magnetic waves when transmitted through certain substances in a magnetic field that has a component parallel to the direction of transmission. Faraday's constant = sense 2 below. Faraday's dark space, Faraday dark space: between the negative glow and the positive column in a low-pressure discharge tube. Faraday's law (a) a law stating that when the magnetic flux linking a circuit changes, an electromotive force is induced in the circuit proportional to the rate of change of the flux linkage; (b) a law stating that the amount of any substance deposited or liberated during electrolysis is proportional to the quantity of charge passed and to the equivalent weight of the substance.
II.
That quantity of electric charge which is required to flow in order to deposit or liberate one gram-equivalent of any element during electrolysis (approx. equal to 96,490 coulomb). E20.
