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 a magnetic field perpendicular to the current. It was discovered by Edwin Hall in 1879.

The Hall Effect can distinguish between positive charges flowing in one direction and negative charges flowing in the other. It is also a common way of measuring the strength of a magnetic field.

Hall effect used in the application of sensors which varies the output voltage in response to the magnetic field and is used for proximity switching, speed detection, positioning, current sensing application etc.

Hal effect is used in sensor application as it is used for current sensing application, positioning, proximity switching, speed detection etc. It is a transducer which varies the output voltage in response to the magnetic field.
