Question

Give reasons for the following: Stationary coil and stationary magnet cannot produce induced electric current.

Answer 1

An electric current is a stream of charged particles, like electrons or particles, traveling through an electrical conductor or space. In electric circuits, the charge transporters are frequently electrons traveling through a wire. The current instigated in a directing circle that is presented to a changing magnetic field is known as induced current.

Complete answer:
Electric current is estimated as the net rate of flow of electric charge through a surface or into a control volume. The moving particles are called charge transporters, which might be one of a few kinds of particles, contingent upon the conductor.

And the several ways to estimate or produce induced current is:
-Change the strength of the magnetic field.
-Moving the conductor in and out of the field.
-Modifying the distance between the magnet and the conductor, or changing the space of a circle situated in a stable magnetic field.

So, the reason behind the fact that stationary coil and stationary magnet cannot produce induced electric current is: to instigate e.m.f and current in the coil, the magnetic flux connected with the coil should change. On the other hand, if both the coil and the magnet are stationary, there is no change in the magnetic flux and consequently, no current is induced in the coil.

Note: The strength of the current induced will rely upon the changing magnetic flux. The direction of the current is dictated by the help of Lenz's law, which says that an induced electric current will flow so that it creates a magnetic field that goes against the change of the field that produced it.
