摘要：
A magnetic ball joint, usable in connection with a convertible stand/table, as well as in other applications, utilizes an array of interleaved magnets and ferromagnetic bodies to both magnetically engage and retain a magnetically-attractive ball using concentrated magnetic force as well as to provide frictional resistance to movement of the ball in the joint.
