Main Idea Electricity is a mystery to many people, even though we use devices that run on electricity every day.
Electricity is a flow of electrons moving in the same direction.
In the early 1800s, a French scientist named Pixii made a discovery. He found that if he rotated a magnet within a metal coil, he could make the electrons in the coil all move in the same direction. He could generate an electric current in the coil. We call this device a generator. If you want to make electricity, you need to make a magnet turn.
