Abstract: A magnetic generator (1) comprising a stator (3), a rotor (5) having an axis of rotation (7); a source of torque to cause rotation of the rotor about the stator; a first set of one or more magnets (9) provided on the stator (3); and a second set of one or more magnets (1 1) provided on the rotor (5). Like poles of the magnets (9, 1 1) face each other and the magnets (9, 1 1) are disposed respectively on the stator (3) and the rotor (5) such that during rotation the rotor (5) is magnetically levitated in relation to the stator (3) by the magnets (9, 1 1). The rotor (5) is ring shaped and an electrically conductive coil (19) is wound around the rotor (5) such that the rotor (5) rotates inside the coil (19).
