Eddy Current Transducer with Rotating Permanent Magnets to Test Planar Conducting Plates [PDF]
Sensors, 2019 In this paper, we present an eddy current transducer with rotating permanent magnets for the inspection of planar conducting plates. The transducer consists of a rotating head with permanent magnets, which is used to generate variable magnetic fields and thus induce eddy currents in the tested material.

LC Resonant-Based Method for Permeability Interference Suppression in Magnetized Pipeline Eddy Current Testing. [PDF]
Sensors (Basel)In the eddy current testing (ECT) of magnetized ferromagnetic pipelines, permeability perturbations near defects cause magnetic distortion that primarily modulates the imaginary part of the ECT sensor’s impedance, leading to confusion between inner and outer wall defect signals.
