Question

Induced electromotive force in a coil does not depend on

• A. Number of turns in the coil
• B. Intensity of the magnetic field
• C. Relative speed between coil and the magnet
• D. Resistance of the coil

Answer 1

The correct option is D Resistance of the coil

Answer is D.

Electromagnetic induction is the production of an electromotive force across a conductor when it is exposed to a varying magnetic field. It is the production of an electric current by changing the magnetic field enclosed by an electrical circuit.
It is a process where a conductor placed in a changing magnetic field (or a conductor moving through a stationary magnetic field) causes the production of a voltage across the conductor. This process of electromagnetic induction, in turn, causes an electrical current - it is said to induce the current.
It depends on Number of turns in the coil, Intensity of the magnetic field and relative speed between coil and the magnet but does not depend on the resistance of the coil.
