However, due to material-related factors, individual strands may corrode and fracture (defects). Magnetic flux leakage (MFL) has proven to be an effective method for defect detection in non destructive testing. A significant challenge lies in detecting defects at depths greater than 20 cm, where detection accuracy is primarily influenced by the design of the MFL sensor.enmagnetic flux leakageconcretedefect detection600 Technik, Medizin, angewandte Wissenschaftenconference paper
