Claim 17:
18. An axial magnetizer module for a smart pig, comprising:
a central shaft; and
at least one magnet bar, coupled to the central shaft at at least one axial end by a set of links, a hinge, and one of a torsion spring or a magnetizer cushion, the magnet bar configured to induce a steady magnetic field coaxially to a longitudinal axis of the central shaft, the at least one magnet bar comprising:
a first magnet of a first polarity circumferentially disposed around a front end of the central shaft;
