The Hall Effect Quiz

The appearance of a transverse electromotive force in the Hall effect is caused by the magnetic force on the free electrons, which leads to the accumulation of electrons on one side of the conductor, producing a transverse electric field (Hall electric field) that opposes the magnetic force on the electrons.

The expression for the magnetic deflecting force in the context of the Hall effect is given by $F_B = q(v_d \times B)$, where $F_B$ is the magnetic deflecting force, $q$ is the charge of the carrier, $v_d$ is the drift speed of the charge carriers, and $B$ is the external magnetic field.

The magnetic deflecting force $F_B$ acts in a direction perpendicular to both the drift velocity $v_d$ and the external magnetic field $B$, according to the cross product $v_d \times B$. This force causes the accumulation of charge carriers on one side of the conductor.

<p>The Hall electric field opposes the magnetic force on the electrons by exerting a force on the accumulated charge carriers, preventing further accumulation and establishing equilibrium in the conductor.</p> Signup and view all the answers

<p>The generation of a Hall electric field occurs when a conducting strip carrying current is placed in a magnetic field perpendicular to the direction of the current. This leads to the accumulation of free electrons on one side of the conductor, producing the transverse electric field known as the Hall electric field.</p> Signup and view all the answers
