Abstract
A magnetic alignment toy comprising a central rotatable wheel having at least two pair of magnets disposed on its circumference, as many peripheral rotatable wheels as there are magnets on the central wheel evenly spaced around the central wheel, each of the peripheral wheels having as many magnets disposed around their circumference as the central wheel has, and a strong master magnet movable around the outside periphery of the peripheral wheels along a path bringing the master magnet into periodic magnetic interactive adjacency to the outermost magnet disposed on each peripheral wheel.

A magnetic alignment toy comprising:
- a central rotatable wheel having at least two pairs of magnets disposed on the circumference of the central wheel, each of the magnets of each pair being disposed in 180 degree relationship to each other;
- as many peripheral rotatable wheels as there are magnets on the central wheel, said peripheral wheels being evenly spaced around the central wheel and each having as many pairs of magnets disposed around its circumference as the central wheel has, and each magnet of each pair being in 180 degree relationship to each other;
- a strong master magnet movable around the outside periphery of the peripheral wheels along a path bringing the master magnet into periodic magnetic interactive adjacency to the outermost magnet disposed on each peripheral wheel;
- wherein the magnets disposed on all of the central and peripheral wheels alternate in polarity around each circumference of the wheels;
- and,
- wherein the peripheral wheels are disposed around the central wheel so as to allow periodic magnetic interactive adjacency of the magnets on the peripheral wheels with the magnets on the central wheel when any of the wheels are rotated.
