The test coil generates analternating electromagneticfield in the test piece =eddy currentBobina de control produce înmaterialul de controlat uncâmp electromagnetic alter-nativ = curent turbionar
A material defect disturbs the path of the eddy currents.This disturbance is detected by the test coil.Un defect de material deranjeaza parcursul curentiilor turbionari.Acest deranjament este preluat de bobina de control
