# Hall Effect Voltage

**Formula:** `V`

_{H} = (I * B) / (n * e * t)

The Hall effect refers to the generation of a potential difference (Hall voltage) across an electrical conductor through which an electric current is flowing, when a magnetic field is applied perpendicular to the current. In this formula:

is the current flowing through the conductor (in amperes).*I*is the magnetic field (in teslas).*B*is the charge carrier density (in carriers per cubic meter).*n*is the thickness of the conductor (in meters).**t**is the Hall voltage across the conductor (in volts).*V*_{H}

The equation is derived from the Lorentz force and is a fundamental principle for magnetic field sensing applications, such as in Hall effect sensors, which are widely used for proximity sensing, positioning, speed detection, and current sensing applications.
