ABSTRACT:
A device for displaying the loose coupling between magnetic fields is provided, comprising a first disk having a plurality of magnetic elements attached to the first disk so that the magnetic field of said magnets extend radially from an outer edge of the first disk, a second disk having a plurality of magnetic elements attached to the second disk so that the magnetic field of said magnets extend radially from an outer edge of the second disk so that the magnets on the disks are loosely coupled to each other, the strength of the loose coupling depending on the orientation of the magnets with respect to each other, and a rotatable control member having a magnetic element attached to an end of the control member, the control member magnet being rotated to a first position such that a predetermined pole of the control member magnet is located adjacent to the magnets on said first disk causing a magnetic coupling of the magnet on said control member to the magnets on said first so that loose coupling and the chaotic motion of the first and second disks are demonstrated.
