A magnetic anti-lock device for a rotating shaft is described. The magnetic anti-lock device utilizes opposing magnets to reduce the varying force required to rotate the shaft and increases efficiency of the rotating shaft. The magnetic anti-lock device includes at least one inner magnet attached to the rotating shaft, and at least one outer magnet fixed in position relative to the rotating shaft. The inner magnet passes the outer magnet each time the shaft rotates creating a repulsive force to reduce the force necessary to rotate the shaft.
