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.
In short, currents help to create magnetic fields. A moving or changing magnetic field does produce a current in a current loop or a voltage across the ends of a current loop. This is called electromagnetic induction and the current or voltage is called an induced current or an induced voltage. Electrical Induction.n short, currents help to create magnetic fields.
