Hall effect British  

noun

1. 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

Hall effect Scientific  

/ hôl /

1. 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).

Example Sentences

In the late 1800s, physicists discovered what is now called the Hall effect.

From Science Daily

This phenomenon became known as the quantum Hall effect.

From Science Daily

Its importance was quickly recognized, ultimately earning three Nobel Prizes in Physics: in 1985, for the discovery of the quantum Hall effect, in 1998 for the discovery of the fractional quantum Hall effect, and in 2016 for the discovery of topological phases of matter.

From Science Daily

As a result, recreating the quantum Hall effect with light seemed extraordinarily difficult.

From Science Daily

The quantum Hall effect already plays a central role in modern measurement science.
