Description

A major advantage of electromagnetic NDE methods, particularly those associated with eddy current or flux leakage inspection, is that the probe does not need to contact the testing specimen. Thus, it allows for rapid moving inspection. However, since the output NDE signals are generated by a moving probe, they are affected by the resulting motionally induced currents and may result in a false interpretation. For this reason, it is necessary to include such velocity effects in numerical field/defect interaction models.
