ELECTROMAGNETIC FIELDS
Electricity is created when charges create electromagnetic fields that act on other charges. There are many types of physics that can cause electricity to occur:
* Electric charge: A property of subatomic particles that determines their electromagnetic interactions. Electromagnetic fields influence and produce electrically charged matter.
* Electric field (see Electrostatics): An extremely simple type of electromagnetic fields produced by an electric charge even though it isn't moving (i.e., there is no current). The electric field exerts a force upon other charges around it.
* Electric Potential: The ability of an electric field or charge to do work, usually measured in volts.
* Electric current: A movement or flow of electrically charged particles. Usually measured in amperes.
* Electromagnets: Magnetic fields are created by moving charges. Magnetic fields are generated by electrical currents, while changing magnetic fields produce electrical currents.
TURBINE GENERATOR
This process is based upon the relationship between electricity and magnetism. Michael Faraday, a scientist, discovered in 1831 that a magnet can be moved within a coil of wire and that electricity flows through the wire. An electromagnet is a magnet made by electricity and used in a typical generator. A series of insulated wire coils form a stationary cylinder. This cylinder is surrounded by a rotating electromagnetic shaft. The coil of wire coils is inducible by the small electric current it generates when the electromagnetic shaft turns. Each section of the wire is a separate, small electric conductor. Each section of the wire is a small, separate electric conductor. Together they form one large current. This is the electricity that is transmitted from power companies to consumers.
