Murphy built a simple motor with a battery, permanent magnet, copper coil of wire and iron bar. when the motor is turned on, the iron bar and coil spin in a circle to produce electricity, explain the energy transformations occurring in the motor

Energy transformation between mechanical energy and electrical energy

Explanation:

Generally, when the copper coil and the iron bar rotate in a circular direction, there is change in the magnetic flux, and as a result an electromotive force (also known as EMF) is generated. The induced electromotive force is the voltage produced due to the presence of magnetic force due to the rotation of the coil and iron bar. Thus, the energy transformation between mechanical energy and electrical energy occurs.
