Find the hall emf

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 …

WebNov 5, 2024 · Find the Hall voltage produced if the pipe runs perpendicular to the Earth’s \(\displaystyle 5.00×10^{−5}-T\) field. ... Once established, the Hall emf pushes charges one direction and the magnetic force acts in the opposite direction resulting in no net force on the charges. Therefore, no current flows in the direction of the Hall emf. WebOne situation where motional emf occurs is known as the Hall effect and has already been examined. Charges moving in a magnetic field experience the magnetic force F = qvB sin θ, which moves opposite charges in opposite directions and produces an em f = Bℓv. We saw that the Hall effect has applications, including measurements of B and v.
