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.
While the generator and the vacuum (or any other device powered by a motor) may serve different functions, they are actually two sides of the same coin. In fact, they are the same device! In an electrical motor, the input is electricity and the output is mechanical power. Contrary to this, a generator takes mechanical power and outputs electricity. In both cases, electricity is flowing - just in a different direction! Electromagnetism. Both motors and generators run because of something called electromagnetic induction. Discovered by Michael Faraday, this is when a voltage is induced by a changing magnetic field. With electromagnetic induction, an electric current can be produced in a coil of wire by moving a magnet in or out of that coil, or by moving the coil through the magnetic field. Either way, voltage is created through motion.
