Question

The phenomenon of electromagnetic induction is:

• A. The production of induced current in a coil due to relative motion between a magnet and the coil.
• B. The process of generating magnetic field due to a current passing through a coil.
• C. The process of charging a body.
• D. The process of rotating a coil of an electric motor.

Answer 1

The correct option is A The production of induced current in a coil due to relative motion between a magnet and the coil.

When a conductor is moved in a magnetic field, then a voltage is induced in it. This phenomenon is called electromagnetic induction. It is an extremely useful phenomenon as it converts kinetic energy to electrical energy.
