What is the function of an electric motor?

To convert electrical energy into mechanical energy

Explain the principle behind the operation of an electric motor.

The interaction between a magnetic field and an electric current generates a force that causes the motor to rotate.

How does an electric motor convert electrical energy into mechanical energy?

An electric motor converts electrical energy into mechanical energy through the interaction between the magnetic field and the current-carrying conductor, resulting in rotational motion.
