“…Signal attenuates rapidly along the direct coupling path, therefore, the signal picked up by the sensor represents the field coming through the tube wall along the indirect coupling path. 3. Similar to what we have seen previously [5] , at beginning of the transit process there is a rapid expansion of the flux lines around the excitation coil and slow penetration of the flux lines through the tube wall .…”

“…Studies, mainly on Finite Element Method (FEM) (2D) approach, have been continued (Atherton et al, 1988;Lord et al, 1988;Sun, 1989). Chen et al (1992) studied changes in the magnetic flux and voltage response in the detector in accordance with time with a sinusoidal excitation frequency of 80 Hz. modeled pipeline corrosion as a slot in the finite element to transform width and depth of the slot into variables to quantify changes in the magnetic vector potential, pointing vector and magnetic field intensity (H).…”
