Abstract: An apparatus having a base with a plurality of magnetic members attached thereto, an arm connected to the base and extending upwardly above the base, and a rigid rod articulated to one end of the arm. The rigid rod has a magnet attached to the end of the rod opposite the arm. This magnet is interactive with the magnetic members of the base. The magnetic members are arranged in a circular pattern within the base. Each of the plurality of magnetic members extends upwardly in the base such that it has a common magnetic pole adjacent an upper surface of the base. A reverse polarity magnet is fastened within the base generally central of the circular pattern of the plurality of magnetic members. The arm has a ball joint that allows the rigid rod to be articulated to the arm. A magnet is affixed to the end of the dowel rod and has a polarity opposite the polarity of the plurality of magnetic members. Indicator pads are provided on the surface of the base adjacent to the plurality of magnetic members.
