2017 Progress In Electromagnetics Research Symposium - Spring (PIERS), 2017
One advantage of remote field eddy current technology is that it is not limited by the skin effect; the technology can be used to detect defects in the inner or the outer wall of a pipeline. Studies have also found the remote field eddy current phenomenon while detecting plate conductors. Remote field eddy current technology is usually used in pipeline

Research in Nondestructive Evaluation, 2018
ABSTRACTIn high-speed magnetic flux leakage (MFL) testing, the tested workpieces pass rapidly through magnetizers. Thus, the magnetization time for workpieces is short. Because of the eddy current effect, the magnetic field inside the workpieces cannot instantly reach equilibrium, and if the magnetizing time is insufficient for the field to reach ...

Eddy Current Magnetic Signature (EC-MS): Experimental tests and Simulations
2021Plastic deformations and residual stresses inevitably occur in metallic components due to industrial machining or heat treatment processes. These local changes of the microstructure affect the real-life performance of industrial parts. Measurements and analysis of residual stresses are necessary for quality assurance and maintenance anticipations.

IEEE Transactions on Applied Superconductivity, 2013
The use of a Superconducting QUantum Interference Device (SQUID) magnetometer for quantitative measurements in eddy-current nondestructive evaluation is presented. The SQUID is used in absolute mode, and the magnetic field measurements are directly compared to theoretical results from both analytical and semi-analytical models.
