ABSTRACT:
A magnet positioning apparatus is provided for positioning a magnet or magnets through a hole in a surface, such as a road surface, a cabinet surface or a curved surface, and into a subsurface region therein. The magnet positioning apparatus includes a main body portion made of a non-magnetic material. The main body portion may be any shape, a hollow cylindrically shaped or plate-/block-shaped with a lower surface shape complementarily corresponding to the shape of a flat or curved surface in which the magnet is to be positioned. If the main body portion is a hollow cylindrical member, the outer periphery of the hollow cylindrical member includes a plurality of arms extending radially outwardly therefrom. In a case where there are three arms, two of the arms may extend outwardly rectilinearly with the third arm extending perpendicularly outwardly from the other two arms. At the outer end of the plurality of arms is a widened portion, and any of the plurality of arms ends in an adjustment member having a threaded hole perpendicularly therethrough which mates with a screw having a rod-shaped portion attached on the head thereof for allowing one full rotation of the screw to adjust the predetermined angle of the magnet positioning apparatus. The magnet positioning apparatus also includes a member for releasably securing a magnet to the main body portion wherein the member is either made of magnetic material or is an electromagnet. The releasably securing member may also include a grasping portion which is scored or roughened and may slidingly nest within the inner diameter of the hollow cylindrical member.
