Question

Electromagnetic induction refers to the:

• A. charging of a body with a positive charge
• B. production of current by relative motion between a magnet and a coil
• C. rotation of the coil of an electric motor
• D. generation of magnetic field due to a current carrying solenoid

Answer 1

The correct option is B

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

Electromagnetic induction is a process where a conductor, placed in a changing magnetic field (or a conductor moving through a stationary magnetic field), causes e.m.f across the conductor leading to the flow of current.

Thus the process of electromagnetic induction causes an electrical current.
