Hall effect (noun) · Hall effects (plural noun)
the production of a potential difference across an electrical conductor when a magnetic field is applied in a direction perpendicular to that of the flow of current.
ORIGIN
early 20th century: named after Edwin H. Hall (1855–1938), American physicist.
The Hall effect is the movement of charge carriers through a conductor towards a magnetic attraction. The phenomenon is named for Edwin Hall, who discovered the effect in 1879. The Hall effect causes a measurable voltage differential across the conductor such that one side is positively charged and the other negatively.
Hall Effect definition. When a magnetic field is applied to a current carrying conductor in a direction perpendicular to that of the flow of current, a potential difference or transverse electric field is created across a conductor. This phenomenon is known as Hall Effect.

What is the Hall effect and what are its applications?
Hall effect finds many applications. It is used to determine if the given material is a semiconductor or insulator. They find applications in position sensing as they are immune to water, mud, dust, and dirt. They are used in integrated circuits as Hall effect sensors. This was the derivation of the Hall effect.
Significance of Hall effects are-. 1) We can identify , whether the conductivity is due to electrons or holes. (for electrons halleffect is –ve, for holes it is +ve) 2) It is used to determine hall voltage, hall current, hall coefficient, hall angle,etc. 3) We can measure magnetic flux density. 4) These devices were capable of being employed ...

A Hall effect sensor (or simply Hall sensor) is a type of sensor which detects the presence and magnitude of a magnetic field using the Hall effect. The output voltage of a Hall sensor is directly proportional to the strength of the field. It is named for the American physicist Edwin Hall.
