ABSTRACT:
A ball and jack set is characterized by a ball which is made magnetic by virtue of an encapsulated magnet, and jacks which have three orgthogonal bars characteristic of most such jacks, but one of the bars is made of a ferromagnetic material, with the other two being plastic. The jacks cooperate with the ball by clinging to it because of the magnetic attraction between the ball and the ferromagnetic arm of the jacks, with the other two arms of the jacks being very lightweight plastic, such that a good balance of magnetic attraction, low production cost, and light weight is achieved. The purpose of the magnetic feature is to permit the user to easily gather the jacks together by simply moving the ball around near or into contact with the jacks until they all cluster together around the ball.
