Magnetic field on the surface of a ring magnet is compressed using a disc magnet having diameter equal to the width of the outer ring. The compressed magnetic field attracts the steel plate fixed on ring magnet making it to rotate. The up and down oscillations of disc magnet is synchronized with rotation of ring magnet thereby making the ring magnet to rotate continuously like a motor. This makes a highly efficient motor because the energy required to oscillate the disc magnet is much less as it is in repulsion with the ring magnet.
