NARRATIVE
       This device consists of a small bar magnet permanently mounted in the base. Another small magnet which is restricted to motion in the vertical plane is mounted above the base magnet so that its north pole lies above the north pole of the base magnet. The resultant of the gravitational and magnetic forces causes the upper bar magnet to float.
