Abstract:
A magnetic particle inspection tool is provided including a yoke with an inspection magnet, a first magnetic member, and a second magnetic member. The inspection magnet is configured to magnetize a work piece. The first magnetic member is rotatable relative to the inspection magnet between a first position and a second position, and the inspection magnet is slidable relative to the first magnetic member. The first magnetic member and second magnetic member include a plurality of magnetic sources forming a magnetic surface with a first magnetic pattern and a magnetic surface with a second magnetic pattern. The magnetic surfaces are magnetically attracted when the first magnetic member is in the first position and repelled when in the second position.
