Haller Article 3. Whena magnetic field is applied to a current carrying conductor in a direction perpendicular to that of the flow of current, a potential differenceor transverse electric field is created across a conductor. The voltage or electric field produced due to the application of magnetic field is also referred to as Hall voltage or Hall field. After fixing the Hall Effect sensor, mark the board with scaled numeric values with the help of marker and scale. "The Hall E ect and Properties of Semiconductors." The Hall effect is the production of a voltage difference (the Hall voltage) across an electrical conductor, transverse to an electric current in the conductor and to an applied magnetic field perpendicular to the current.
