What is the Hall Effect?
The Hall Effect is a phenomenon in which a current-carrying conductor, when placed in a magnetic field, generates a voltage across its length, perpendicular to both the current direction and the magnetic field direction. This voltage is known as the Hall voltage.
The Hall Effect is caused by the interaction between the magnetic field and the moving charge carriers (electrons) in the conductor. The magnetic field deflects the charge carriers, creating a voltage difference across the conductor.
