The Hall effect is due to the nature of the current in a conductor. Current consists of the movement of many small charge carriers, typically electrons, holes, ions (see Electromigration) or all three. When a magnetic field is present, these charges experience a force, called the Lorentz force. When such a magnetic field is absent, the charges follow approximately straight paths between collisions with impurities, phonons, etc. However, when a magnetic field with a perpendicular co… WebFeb 5, 2024 · Hall Effect Derivation Hall effect is defined as the production of a voltage difference across an electrical conductor which is transverse to an electric current, and …
