The machine at the heart of almost every power station, converting mechanical rotation into electric current by electromagnetic induction: moving a magnet relative to a coil of wire induces a current in the wire, the principle Michael Faraday demonstrated. Steam, water and gas turbines exist to spin generators, which is why most of the world's electricity arrives through one.

In addition to its most common usage for electromechanical generators described above, the term generator is also used for photovoltaic, fuel cell, and magnetohydrodynamic powered devices that use solar power and chemical fuels, respectively, to generate electrical power.

He found that moving a magnet inside a coil of wire makes (induces) an electric current flow through the wire.
Electricity explained, How electricity is generated
Most U.S. and world electricity generation is from electric power plants that use a turbine to drive electricity generators.
