Hall Effect Derivation - Method, Applications and FAQ - Vedantu

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… Tīmeklis2010. gada 16. apr. · V 24P = Hall voltage measured between leads 2 and 4 with magnetic field positive for I 13.
