This device converts the intrinsic magnetic force of permanent magnets into a useful output. The three-pole permanent magnets configuration comprises of two elongated bar magnets (1,2) having two opposite magnetic polarities divided by a longitudinal plane. One magnet (1) is referred to as the movable magnet and the other magnet (2) is referred to as the stationary magnet and is located juxtaposed and perpendicular to a broad side surface of the movable magnet. The interaction of the intrinsic magnetic forces of the two magnets (1,2) results in a torque forcing the movable magnet to move in its longitudinal direction (37) relative to the stationary magnet. A plurality of such three-pole permanent magnets configurations are provided around the periphery of a rotary wheel (8) to provide a rotary torque output. |
