Michael Faraday discovered in 1831 that if a "coil" of Copper Wire is rotated in a Magnetic Field in such a way as to cut across the "lines of magnetic force," an electric charge is created or induced in the Wires. This is the basic principle by which practically all our present day electric current is generated.
Generators use "magnetic induction" to produce electrical energy. Moving Wires through a Magnetic Field generates electrical current. The Wire "loop" inside the Generator is mechanically driven by some source of rotary motion. The source of power for the rotation might be fossil fuels, falling water, or nuclear energy. As the Wire loop spins inside the Magnetic Field, an electric current is produced in the Wire. This current becomes the basis for commercially available electrical energy. |
