A device that uses electricity and magnetism to create motion is called a motor . In a reverse process, a device that uses motion and magnetism can be used to create electricity

Explanation:

A motor is a device that uses electricity and magnetism converts it to mechanical energy. A current carrying wire is placed between two magnets. A force is produced which causes the current carrying wire to rotate. Motor is used to pull water in pipelines.

In the reverse process, a generator uses motion and magnetism to produce electric current. When a conducting wire is placed between changing magnetic field, electromotive force is induced which causes electricity to flow in the wire.

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray
