description Apparatus and methods for magnetic wall inspecting materials such as cylindrical and tubular members are disclosed. One apparatus includes a main magnetic coil producing lines of magnetic flux able to traverse a section of a tubular member in a direction generally parallel to a longitudinal axis of the tubular member; and one or more magnetic focusing members positioned along the tubular and able to redirect certain flux lines so that they are more parallel to the tubular. This abstract allows a searcher or other reader to quickly ascertain the subject matter of the disclosure. It will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).
