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]
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.
Sep 12, 2022 · Compare how charge carriers move in a conductive material and explain how this relates to the Hall effect. 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.
May 3, 2024 · The Hall Effect refers to generating a voltage perpendicular to an electric current flowing in a conductor and a magnetic field applied perpendicular to the current. It is a manifestation of the interplay between electric and magnetic fields, fundamentally altering the behavior of charged particles moving within a conductor.
4 days ago · Hall effect, development of a transverse electric field in a solid material when it carries an electric current and is placed in a magnetic field that is perpendicular to the current. This phenomenon was discovered in 1879 by the U.S. physicist Edwin Herbert Hall.
Feb 20, 2022 · The Hall effect is the creation of voltage \(\varepsilon\), known as the Hall emf, across a current-carrying conductor by a magnetic field. The Hall emf is given by \[\varepsilon = Blv\nonumber\] with \(B\), \(v\), and \(l\) all mutually perpendicular for a conductor of width \(l\) through which charges move at a speed \(v\).
The transverse voltage (Hall effect) measured in a Hall probe has its origin in the magnetic force on a moving charge carrier. The magnetic force is F m = ev d B where v d is the drift velocity of the charge.
The Hall effect is used today as a research tool to probe the movement of charges, their drift velocities and densities, and so on, in materials. In 1980, it was discovered that the Hall effect is quantized, an example of quantum behavior in a macroscopic object.
