Effect of excitation frequency on magnetic response induced by front-and back-side slits measured by a differential AMR sensor probe

Effect of excitation frequency on magnetic response induced by front-and back-side slits measured by a differential AMR sensor probe

Defects in steel structures is one of the major problems that may affect the functionality of the structure. Thus, the detection of the defects is fairly crucial to prevent any unwanted accident from occurring. Nondestructive Testing (NDT) is a group of methods that is widely used in order to detect...
