| Abstract: | The feasibility of the eddy-current nondestructive testing using two orthogonal harmonic components of the driving magnetic
field has been studied. The paper describes the practical implementation of the method in a flaw detector testing ferromagnetic
rods and pipes and designed for detecting elongated flaws with small gradients of longitudinal parameters. |
