Actuator: Motor

Motors are small machines that take electrical energy and turn it into mechanical movement with the help of a magnet, and a coil of wire. Motors need a source of  power (such as a battery, solar energy, or a wall plug) and a coil of wire to generate an electromagnetic force that turns a motor part around and around, or pushes it in a particular direction. A motor is an example of an actuator. Motors are commonly found in cars, airplanes, toys, and electric toothbrushes. In your motor, where is the current coming from? What part is going around and around?

Electric motors turn electricity into motion by exploiting electromagnetic induction.
