reverb effect

The Hall effect is a phenomenon named after the American physicist Edwin Herbert Hall (1855 to 1938) and shows the magnetic influence on current-carrying lines. The phenomenon of the Hall effect is based on the Lorentz force. It occurs when charge carriers move perpendicular to a magnetic field.

When the charge carriers move perpendicular to the magnetic field, a force acts on the charge carriers whose direction is orthogonal to both the magnetic field and the direction of motion of the charge carriers.

Generation of Hall voltage by magnetic flux and current flow

Due to the Lorentz force, a charge displacement takes place in Hall sensors. This results in an electric field which exerts a force on the charge carriers which opposes the Lorentz force. An equilibrium is established between these two forces. If contacts are attached to the long sides of the Hall element, the Hall voltage is applied to them. The magnitude of the Hall voltage is proportional to the Lorentz force and a measure of the density of the magnetic flux.

The Hall effect is used, among other things, in Hall sensors for current measurement, as well as in joysticks and magnetometers.
