**Hall potential or voltage:** If a magnetic field is applied perpendicular to the flow of current, then a potential or voltage is created normal to both that current and the magnetic field. This effect is called the Hall effect and the generated potential or voltage is called Hall potential or Hall voltage.

Hall potential or voltage is the no-load voltage developed across a semiconductor plate due to the Hall Effect, when a specified value of control current flows in the presence of a particular magnetic field. Hall potential difference observed between the edges of a conducting strip carrying a longitudinal current when placed in a magnetic field perpendicular to the plane of the strip.

The Hall Effect is the construction of a hall potential or voltage, across an electrical conductor, transverse to an electric current in the conductor and to an applied magnetic field perpendicular to the current
