Hall effect


noun Physics, Electricity.

the electromotive force generated in a strip of metal longitudinally conducting an electric current and subjected to a magnetic field normal to its major surface.

Origin of Hall effect

1900–05; named after Edwin H. Hall (1855–1938), American physicist who discovered it

British Dictionary definitions for hall effect

Hall effect

noun

the production of a potential difference across a conductor carrying an electric current when a magnetic field is applied in a direction perpendicular to that of the current flow

Word Origin for Hall effect

named after Edwin Herbert Hall (1855–1938), American physicist who discovered it

Scientific definitions for hall effect

Hall effect
[ hôl ]

A phenomenon that occurs when an electric current moving through a conductor is exposed to an external magnetic field applied at a right angle, in which an electric potential develops in the conductor at a right angle to both the direction of current and the magnetic field. The Hall effect is a direct result of Lorentz forces acting on the charges in the current, and is named after physicist Edwin Herbert Hall (1855-1938).
