The effects of remanent magnetization on magnetic flux leakage signals

NDT & E International, 1997
The Magnetic Flux Leakage (MFL)Technique is the most commonly used technique to inspect large diameter transmission pipelines [1–5]. A typical MFL inspection system uses permanent magnets to apply an axially oriented magnetic field to the ferromagnetic pipe material.
