An electrical generator creates electricity by A) By spinning a turbine with kinetic energy

B) By using Gasoline

C) By exposing a coil of wire to a changing magnetic field

D) By Aligning the magnetic domains of the coil of wire

C) By exposing a coil of wire to a changing magnetic field

Explanation:

An electrical generator creates electricity by exposing a coil of wire to changing magnetic field.

The generator converts mechanical energy which the energy due to the motion of a body and this produces electrical currents.
