Explanation

When the current passes through the conductor perpendicular to the external magnetic field, there will be a potential difference between the two ends of the conductor perpendicular to the magnetic field and the current direction, which is known as the Hall effect. It defines the relationship between magnetic field and induced voltage, which is completely different from traditional electromagnetic induction. When an electric current passes through a conductor located in a magnetic field. A magnetic field will exert a force perpendicular to the direction of electron motion on electrons in a conductor, resulting in a potential difference in two directions perpendicular to the conductor and magnetic induction line. This potential difference is also known as the Hall potential difference.
