Question

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

Answer 1

Answer:

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.

• In the presence of a magnetic field electric current is induced within the circuit.
• The mechanical energy is obtained from an external source and sustained by the turning of the pistons with the set up.
• This keeps the generator in constant motion and through the magnetic fields.
