Magnetizers may include a cushion disposed about the shaft and biasing the magnet bar against a pipe wall. A sensor head disposed between circuit poles at each polar end of the magnet monitors magnetic flux. The central shaft of a circumferential magnetizer or axial magnetizer may comprise a joint linking an additional smart pig module. A novel magnetizer cushion is described, as are smart pigs containing one or more circumferential or axial magnetizers."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Magnetizer with cushion","description":"Circumferential and axial magnetizers for a magnetic flux leakage pig.
