  1. The principle of the Hall effect states that when a current-carrying conductor or a semiconductor is introduced to a perpendicular magnetic field, a voltage can be measured at the right angle to the current path. This effect of obtaining a measurable voltage is known as the 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. [1] [2]

  3. Jul 16, 2024 · Hall Effect. 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.

  4. Jul 9, 2024 · We investigate the Hall effect by studying the motion of the free electrons along a metallic strip of width l in a constant magnetic field (Figure \(\PageIndex{1}\)). The electrons are moving from left to right, so the magnetic force they experience pushes them to the bottom edge of the strip.

  5. Apr 17, 2020 · The Hall Effect is the electric polarization of a block or slab of metal that occurs when a current is run through it while it is subject to a magnetic field perpendicular to the current. The Main Idea.

    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.

  7. 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 \(v\).

    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.

  9. 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.

  10. Hall Effect, deflection of conduction carriers by an external magnetic field, was discovered in 1879 by Edwin Hall. It has been known that moving carriers in a magnetic field are accelerated by the Lorentz Force, and the magnitude and the direction of the applied force on the carriers are given as in Equation (1):
