When a charged particle moves on uniform magnetic field (B), it experience a force F as F= Bqv sinΘ, where q is charge particle, v be its velocity and Θ be is angle between B and v. This force is acting toward the motion of the circle or motion is circular. The direction of force F and distance covered s are always perpendicular to each other such that, work done W = FS cos90 = 0. so, the magnetic force does no work done but moves the particle in circular motion.

An induced current is a current that is produced in a conductor when there is a change in the magnetic field surrounding it. Unlike a direct current (DC), which flows continuously in one direction, an induced current is alternating in nature and changes direction periodically. The direction of an inRead more
An induced current is a current that is produced in a conductor when there is a change in the magnetic field surrounding it. Unlike a direct current (DC), which flows continuously in one direction, an induced current is alternating in nature and changes direction periodically.
The direction of an induced current is not determined by the current itself but is instead determined by the direction of the changing magnetic field that is causing the current. According to Faraday’s law of electromagnetic induction, the magnitude and direction of an induced current are proportional to the rate of change of the magnetic field. The induced current will flow in a direction such that it opposes the change in the magnetic field that produced it, as described by Lenz’s law.
Therefore, the direction of the induced current is not determined by any intrinsic property of the current itself, but rather by the external factors that are causing it to be induced.
