ABSTRACT:
A method of and apparatus for non-destructive investigation of the surface properties of a body of ferromagnetic material such as a pipeline in which a non-saturating source of magnetic flux is placed adjacent to said surface to create a magnetic circuit having a substantial proportion in non-ferromagnetic material and a sensor is used to measure the magnetic flux in said circuit, an indication of the surface properties of the body being derived from a plurality of such measurements.
