Define hall effect
The Hall effect is the production of a potential difference (the Hall voltage) across an electrical conductor that is transverse to an electric current in the conductor and to an applied magnetic field perpendicular to the current. It was discovered by Edwin Hall in 1879. This is sometimes termed the ordinary Hall … See more The modern theory of electromagnetism was systematized by James Clerk Maxwell in the paper "On Physical Lines of Force", which was published in four parts between 1861 and 1862. While Maxwell's paper established a solid … See more The Hall effect is due to the nature of the current in a conductor. Current consists of the movement of many small charge carriers, … See more The Corbino effect is a phenomenon involving the Hall effect, but a disc-shaped metal sample is used in place of a rectangular one. Because of its shape the Corbino disc allows the observation of Hall effect–based magnetoresistance without the associated Hall … See more • Introduction to Plasma Physics and Controlled Fusion, Volume 1, Plasma Physics, Second Edition, 1984, Francis F.

The positive and negative charges drift to opposite ends of the conductor producing a hall voltage when a magnetic field is applied. An equation for the Hall voltage VH is derived from the electric and magnetic forces on the charges. The electric and magnetic forces on the electrons are equal and opposite.
