Answer:
D) Spinning a coil of wire near a large magnet.
Explanation:
From Faraday's law of induction, when a conducting coil of wire is placed in changing magnetic flux, an emf is induced which produces current in the coil.
Induced emf is given by:
A generator is based on the same principle.
The mechanical energy of rotating coil is converted to electrical energy when current is induced. Thus, the correct option is D) Spinning a coil of wire near a large magnet.
