In this activity, students will investigate the principles that make electric motors possible.
Perhaps the most important invention of the 19th century was the electric motor. You use a motor whenever you use electric power to make something move. A motor is used to start the engine of a car. Motors are used to spin compact discs. Motors are used to move elevators up and down. A list of motor applications would go on and on. But how do motors turn electric energy into mechanical energy? Let's find out!
