ABSTRACT:
Apparatus for performing nondestructive magnetically testing and inspection of elongate objects. The apparatus concentrically surrounds the elongate object to be tested and includes means for inducing a magnetic field in the elongate object and a partial ferrous return path for the magnetic flux emanating from a pair of magnet arrays. The partial ferrous return path is engaged with a sensor for detecting variations or flaws in the elongate object.
