Question

An electric generator transforms mechanical energy into electrical energy. This process could be done by which of these?

Answer 1

Answer:

its d

Explanation:

Answer 2

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:

$e = -\frac{d\phi}{dt}$

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.
