A magnetic sensing technology invented by American physicist Edwin Hall in 1879, the Hall Effect principle is the differential voltage generated in a current-carrying conductor when applying a perpendicular magnetic field. The voltage is a result of a Lorentz force from the applied magnetic field, which causes current electrons to concentrate in one end of the conductor and generate a potential difference between the two ends.

When a magnetic field isn’t present, current electron distribution is uniform, and Hall voltage is zero. When a magnetic field is applied, current electron distribution is disturbed and will result in a non-zero Hall voltage proportional to the cross product of the current and the applied magnetic field. The current is usually fixed, resulting in a direct relationship between Hall voltage and the applied magnetic field.
