Generators Experiments with motors Generators Electric generators are used to efficiently convert mechanical energy into electrical energy.
Magnetism is the basis of their principles of operation.
They use permanent magnets, electromagnets, and exploit the magnetic properties of materials in order to create these amazing machines. The generators used to produce the voltages used in your home and in industry are large units, usually connected to a turbine which is powered by steam. Two-phase Used in the emergency home generators , provides two 120V circuits which are combined to give a 240V circuit. This is the Right Hand Rule for generators. So, when a wire moves perpendicular to a magnetic field, cutting through the magnetic field lines, a voltage is induced across the wire.
