Question

Which of the following statements describes an electric generator?
A. A magnet is rotated through a coil of wire to produce an electric current.
B. Electric potential in a rotating coil of wire creates a permanent magnet.
C. An electrical current causes a coil of wire to rotate in a magnetic field.
D. Forces from a permanent magnet allow a coil of wire to rotate.

Answer 1

An electric generator is when a magnet is rotated through a coil of wire to produce an electric current.

Answer 2

Answer:

A. A magnet is rotated through a coil of wire to produce an electric current.

Explanation:

An electric generator works on the principle of Faraday's law of induction. As the magnetic flux linked with the coil changes, an emf is induced in the coil and current is produced.

An electric generator converts mechanical energy to electrical energy.

Thus, the correct statement that describes the an electric generator is: A. A magnet is rotated through a coil of wire to produce an electric current.
