(metrology) An SI unit of electrical capacitance equal to 10⁻⁹ farads. Symbol: nF

(physics) An interaction between a polarized electromagnetic pulse, such as a beam of light, and a magnetic field, in which the plane of polarization is rotated in proportion to the intensity of the component of the magnetic field in the direction of travel of the pulse.

plural of Faraday rotation

The dark space in a glow discharge that is between the negative glow and the positive column.

plural of Faraday dark space

plural of Faraday bag

A bag made of a material that blocks electromagnetic signals, and employing special sewing techniques such as dual paired seam construction, used to hold devices such as cell phones in order to prevent outside signals from interfering with the contents of the device.

plural of Faraday cage

(physics) A second rank, four dimensional, antisymmetric tensor which may be expressed as a four-by-four array containing the components of the electric field and the magnetic field.

A pointer or torch/flashlight powered by a battery that may be recharged by shaking.
