Flexible planar eddy current probes are widely used to detect conductive components with complex surface. In this study, topological transformation is applied to design a differential Koch coil exciting eddy current probe. Two kinds of Koch exciting coils, Koch A and Koch B , were obtained by topological transformation from a three-dimensional differential exciting eddy current probe. Finite element model simulation is conducted to visualize the differences of eddy current distributions induced by the probes and get the defect signal. A detailed comparison is made among the two kinds of Koch e

Conventional eddy current bobbin probes, multi-pancake and/or rotating pancake probes, and transmit-receive eddy current probes are currently utilized in testing metal tubing.

Abstract:
The distribution of eddy currents induced in metal by a surface multiple-unit eddy current probe (ECP) is investigated. A mathematical formula is derived to calculate the increment in the magnetic moment of the eddy currents within the metal, accounting for the mutual interactions and orientation of the individual eddy current probes within the ECP array. The results indicate that the increment in the magnetic moment of the eddy currents increases monotonically as the spacing between the probes in the ECP array decreases, while the sign of the magnetic moment increment is determined by the pha

Vector fields found in electromagnetics are fundamentally different to vector fields found in other research areas such as structural mechanics. Electromagnetic vector fields possess different physical behaviour patterns and different properties in comparison to the other vector fields and therein lies the necessity of the development of a finite element which would be able to cater for these differences . The vector finite element was then developed and used within the finite element method specifically for the approximation of electromagnetic problems. This dissertation investigates the part

Abstract:
This article elucidates on the concept of electromagnetism and electromagnetic induction with a view to explaining the theory of magnetic stimulation, used to cure diseases in human beings. Magnetic stimulation follows the principles of electromagnetism. A changing primary current induces secondary currents, which are called eddy currents, in the nearby conductors (human tissue in this case). The strength of the electric field is measured by its electromotive force (emf), which in turn, is measured in volts. The changing primary current also gives rise to an induced voltage in the primary loop

Abstract Cracks may occur in the back of turbine blades during the manufacturing process, which may cause potential safety hazards to the aero-engine. To design proper probes for detecting the back-side crack, this paper builds a finite-element model for eddy current detection of cracks on the back of the nickel-based superalloy plate, which are often used to produce blades. The influence of coil parameters and crack parameters on eddy current signal is investigated. The results show how to choose the proper parameters of a coil and how crack parameters affect eddy current signals.

Abstract:
This report deals with a novel and rather unorthodox electromagnetic inspection technique called the Se/f-Excited Eddy Current (SEEC) or Motion Induced Eddy Current (M/EC) method. The SEEC approach promises a surprisingly simple solution for the difficult and long-standing SCC detection, characterization, and discrimination problem.

Abstract:
Presents the results of an investigation to exploit the potential for using the increased sensitivity to inner and outer pipe wall in homogeneities of remote field eddy current technology to detect stress corrosion cracking. The investigation is focused on the application of finite element analysis to RFEC probe simulation and design. See also L51513.

Abstract:
When an eddy current probe is placed near a conductive material, the alternating magnetic field from the probe causes electrical currents to flow in the material. These currents have associated with them their own magnetic field, which opposes the original magnetic field from the coil. The result is that the impedance of the probe is greatly reduced by the presence of the conducting material. If the conductor is also magnetic, as is normal steel, the situation is similar though slightly more complicated. Here, the impedance of the probe may be either increased or decreased depending on the per
