WebThe Hall emf if proportional to both the diameter and the average velocity. A current-carrying wire is in a uniform magnetic field. Initially, the field is perpendicular to the direction of the current. The field then shifts so that it is directed to an angle 30∘ to the direction of the current. How does the force per unit length on the wire ... WebFeb 17, 2024 · Hall effect, development of a transverse electric field in a solid material when it carries an electric current and is placed in a magnetic field that is perpendicular to the current. This phenomenon was discovered in 1879 by the U.S. physicist Edwin Herbert Hall. The electric field, or Hall field, is a result of the force that the magnetic field exerts …
