Answer:
The principle of an electric motor is based on the current-carrying conductor which produces magnetic field around it. A current-carrying conductor is placed perpendicular to the magnetic field so that it experiences a force.
Explanation:
In this exercise we have to use the knowledge of electric motors and explain that they work through a closed circuit and a source.
Electric motors are electrical machines that transform electrical energy into mechanical energy. There are many types of electric motors, and we can basically separate them into three large groups which are direct current motors, alternating current motors and universal motors.
In a simpler way, we can say that they are motors that use a closed system that has a source and an electric current.
