This is the basis of generation in rotating machines. You can produce a current in a conductor by connecting opposite ends to the + and-poles of a battery, but don't try this with your car battery or you will burn out the conductor and produce a lot of heat. It is safer to use a small dry battery.
When electrons move through a conductor an electric current is created. A current that always flows in one direction is called a direct current (DC). A battery for example, produces a direct current. A current that flows back and forth is called an alternating current (AC).
