ABSTRACT:
A method for locating a device producing a magnetic field in a blind or inaccessible position of a work piece. A magnet is initially placed on a first side of the work piece such that a magnetic field produced by the magnet extends through the work piece. Probes are then positioned over a second surface of the work piece to determine the location of the axis of the magnet via the strength of the sensed magnetic field and the location where the strength measurements are made. Once the position of the axis of the magnet is determined, the work surface is either marked or worked on through the platform on which the probes are positioned. In particular, the present invention allows a very accurate positioning of a work tool on the second surface without the need to first visualize the first surface of the work piece.
