Permanent magnet generators

A permanent magnet generator (PMG) uses strong magnetic fields created by permanent magnets, instead of electric currents, to generate electricity. When its rotor (the spinning part) turns inside the stator (the stationary part), the magnetic field changes around the coils of wire in the stator. This changing magnetic environment induces an electric current, producing electricity. PMGs are efficient, reliable, and require less maintenance because they don't need external power to create magnetic fields. They are commonly used in wind turbines, small-scale power setups, and other renewable energy systems for clean, consistent electricity generation.
