Abstract

Abstract A permanent magnet propulsion system wherein a steel ball is propelled up an inclined plane between two rows of permanent bar magnets, said magnets being in spaced relationship with all north seeking poles of one of the said rows facing in substantially the same direction and with all south seeking poles in the other row facing in substantially the same but opposite direction to the first of said rows. The magnetic axes of each of the magnets of the first said row are in staggered relationship to the axes of opposing magnets of the second said row. The magnetic field acting on the ball is configured whereby the ball after reaching the top of the inclined plane is able to drop from the said plane out of the field. A pair of parallel tracks positioned between the spaced rows of magnets guide the ball and a clamping means orient and retain the magnets.
