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.
What is Alternating Current. Alternating current has a constant voltage, but constantly changes position between positive and negative polarities, producing a wave when represented visually. Electric current is transmitted around the country in the form of alternating current. 120 volts and 60 cycles (position changes between polarities positive to negative to positive) per second (60 Hz) alternating current is what is the most common power source that is supplied to United States residential homes.
