Hall effect is a process in which a transverse electric field is developed in a solid material when the material carrying an electric current is placed in a magnetic field that is perpendicular to the current. The Hall effect was discovered by Edwin Herbert Hall in 1879.
In 1879, E.H. Hall devised an experiment that can be used to identify the sign of the predominant charge carriers in a conducting material. From a historical perspective, this experiment was the first to demonstrate that the charge carriers in most metals are negative. Visit this website to find more information about the Hall effect.
In this experiment, the Hall Effect will be used to study some of the physics of charge transport in metal and semiconductor samples. In 1879 E. H. Hall observed that when an electrical current passes through a sample placed in a
Jul 16, 2024 · The Hall effect occurs when a magnetic field is applied at a right angle to an electric current flowing through a conductor, creating a voltage across the conductor. This phenomenon shows how electric and magnetic fields can influence the movement of charged particles in a material.
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. [1] [2]
Apr 15, 2010 · The basic physical principle underlying the Hall effect is the Lorentz force, which is a combination of two separate forces: the electric force and the magnetic force. When an electron moves along the electric field direction perpendicular to an applied magnetic field, it experiences a magnetic force - q v X B acting normal to both directions.

Introduction. In 1879, E. H. Hall observed that when a current-carrying conductor is placed in a transverse magnetic field, the Lorentz force on the moving charges produces a potential diference perpendicular to both the magnetic field and the electric current.
In 1879, E. H. Hall observed that when a current-carrying conductor is placed in a transverse magnetic eld, the Lorentz force on the moving charges produces a potential di erence perpendic-ular to both the magnetic eld and the electric current. This e ect is known as the Hall e ect [1].
The Hall effect can be used to measure the average drift velocity of the charge carriers by mechanically moving the Hall probe at different speeds until the Hall voltage disappears, showing that the charge carriers are now not moving with respect to the magnetic field.
