The generation of electricity through the rotation of a ____ within a coil of wire is based on the principle of ____ ____. When a magnet is moved relative to a coil of wire, a changing magnetic field is created, which ____ an ____ current in the wire. When the magnet ____ within the coil of wire, the ____ ____ passing through the coil changes. This change in magnetic field induces an electric ____ in the wire. Similarly, when a coil of wire is moved within a magnetic field, a changing magnetic field is again created, resulting in an ____ electric current in the wire. The induced voltage is determined by the rate of change of magnetic field and the ____ of ____ in the coil.
