Question

Electromagnetic induction is involved in ______.

Options

• charging a body with positive charge

• production of current by the relative motion between a magnet and the coil

• rotation of the coil of an electric motor

• generation of magnetic field due to a currentcarrying solenoid

Answer 1

Electromagnetic induction is involved in production of current by the relative motion between a magnet and the coil.

Explanation:

Electromagnetic induction is the phenomenon of producing an induced emf in a coil due to a change in the magnetic flux linked with it. When a magnet and a coil move relative to each other, the magnetic flux changes, inducing an electric current in the coil if the circuit is closed.
