Magnetic Field

Describe Hall Effect along with its derivation .

The Hall Effect, also called the Hall–Heroult effect, is the influence of the transverse component of an electric current on the magnetic field in a transverse Hall bar. When a current flows in a plane perpendicular to the direction of the magnetic field, the Lorentz force acts on the magnetic charges (magnetic flux) enclosed by the transverse current.

The Lorentz force is the force experienced by a magnetic charge when acted upon by an external force field, which in this case is the...

Write down expression of acceleration of a moving charge Q in a parallel and perpendicular magnetic field.

The expression for the acceleration of a moving charge Q in a magnetic field depends on the direction of the magnetic field relative to the velocity of the charge. Here are the expressions for the acceleration of a moving charge Q in a parallel and perpendicular magnetic field:

1. Parallel Magnetic Field:

If the magnetic field is parallel to the velocity of the charge, the charge experiences a force that causes a centripetal acceleration. The expression for the acceleration (a_parallel) is...
