Abstract
A dish-shaped magnet in one form has an upper surface of a first polarity and a lower surface of a second polarity disposed in co-axial relationship to a second magnet having the opposite polar relationships. The magnetic fields in one form of the invention position the second magnet in spaced relation to the dish-shaped magnet. The apparatus has application as a novelty as well as for gyroscopic and other instrumentation apparatus wherein friction must be minimized. The upper magnet may be rotated either manually or by associated apparatus to provide gyroscopic stability.
