Abstract
In accordance with one embodiment, the present technique provides a testing apparatus for testing material integrity in an object. The testing apparatus includes an electrical conductor and a sensing device. In the exemplary testing device, the electrical conductor extends in a generally linear direction and is configured to route current in a direction generally transverse to a longitudinal axis of the object being tested. Routing of current through the electrical conductor creates remote field eddy current effect, which, in turn, affects a magnetic field around the test object. The testing apparatus also includes a sensing device located at a distance from the electrical conductor and configured to detect magnetic fields generated in response to current routed through the electrical conductor.
