This invention teaches that utilizing a rotating spherical or a rotating wheel permanent magnet means disposed in the centre of a coil-wire form disposed with focus magnets generates electrical power; and the design of said spherical permanent magnet can be of a solid rare earth magnetic material or of a non-magnetic material with a central cylinder magnet disposed its central through hole; and the design of said wheel magnet can utilise either a single centralised cylinder magnet or a series of central small centralised cylinder magnets in a circular array around said wheel. Further said present invention can be utilised as a power source for a battery-less and wireless switch means, and further said invention can be utlised in a scaled up version for larger power sources for vehicles, sea craft, aircraft, caravans, mobile homes,and homes.
