Abstract
This paper describes an experimental teaching material produced experimentally with a view of improving the operation of the commercial products (trade name: U-CAS (No.1), SUPER LEVITRON (No.2) and LEVITRON ZERO (No.3)) associated with magnetic coma levitation. The effect of the magnetic force was examined at the place where the magnetic coma turns and the place where the magnet coma floats. The magnetic flux density distribution was measured in vertical direction (about 50〜70mm on the central axis from the base) and in horizontal direction at the place where the magnet coma floats and at the place where the magnet coma rotates. In the region where the magnet coma turns, 1) in the perpendicular characteristic, the magnetic force of the N magnetic pole rises nearly to its largest value, and 2) the central part becomes somewhat concave in the horizontal direction. In the vicinity of where the magnet coma floats, 1) there is a small change in the magnetic N pole force in the perpendicular direction, with 2) this force being almost uniform in the horizontal direction.
