GEOLOGY

Detailed explanation-1: -Moving a magnet around a coil of wire, or moving a coil of wire around a magnet, pushes the electrons in the wire and creates an electrical current. Electricity generators essentially convert kinetic energy (the energy of motion) into electrical energy.

Detailed explanation-2: -An electric generator or electric motor consists of a rotor spinning in a magnetic field. The magnetic field may be produced by permanent magnets or by field coils. In the case of a machine with field coils, a current must flow in the coils to generate the field, otherwise no power is transferred to or from the rotor.

Detailed explanation-3: -Most of world electricity generation is from generators that are based on scientist Michael Faraday’s discovery in 1831 that moving a magnet inside a coil of wire makes (induces) an electric current to flow in the wire.

Detailed explanation-4: -When the coil rotates, it cuts the magnetic field which lies between the two poles of the magnet. The magnetic field will interfere with the electrons in the conductor to induce a flow of electric current inside it.

Detailed explanation-5: -The rotor generates a moving magnetic field around the stator, which induces a voltage difference between the windings of the stator. This produces the alternating current (AC) output of the generator.
