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.

2024年8月11日 · The Hall effect occurs when a magnetic field is applied at a right angle to an electric current flowing through a conductor. As a result, a voltage is created across the conductor, perpendicular to both the electric current and the magnetic field.

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 11.7.1 11.7. 1). The electrons are moving from left to right, so the magnetic force they experience pushes them to the bottom edge of the strip.

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.

2025年3月1日 · 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.

2023年10月17日 · The Hall effect is a fundamental physics phenomenon observed when a magnetic field is applied perpendicular to the direction of the current flow in a conductor or semiconductor. It results in the generation of a voltage perpendicular to …

2010年4月15日 · The Hall Effect and the Lorentz Force. 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.

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.

2024年12月18日 · It is the generation of potential difference across electrical conductors, traversed to electric current in the conductor and to the magnetic field perpendicular to current. The voltage produced is called Hall voltage. The Hall effect was given by E. H. Hall in 1879.
