Magnetic flux leakage testing (MFLT) is an important nondestructive testing method for the detection and evaluation of defects in magnetic materials. Magnetic field distribution in an MFLT system is usually simulated by the finite element method (FEM), which required large memory, high computation, ...
1.1 Magnetic Flux Leakage (MFL) technology has been used in the monitoring of Underfloor or Far Side (FS) corrosion for about 11 years. Silverwing (UK) Ltd entered the field ten years ago, in 1991. As with all Non Destructive Testing methods, MFL has both advantages and disadvantages,...
