Abstract
A device, system and method for detecting flaws in a magnetic material includes a wheeled scanner having two detectors and arranged for travel over a flat surface. The first detector is a horizontal magnet-sensor arrangement that generates a magnetic field in a direction generally parallel to a central horizontal axis of the scanner. The second is a vertical magnet-sensor arrangement that generates a magnetic field in a direction generally perpendicular to the central horizontal axis of the scanner. A set of computer executable instructions uses data collected by the first detector to detect a flaw in the magnetic material and data collected at a same time by the second detector to determine a location of the detected flaw relative to a top and bottom surface of the magnetic material.
