چکیده
This paper presents a distributed current source (DCS) method for modeling the eddy (EC) fields induced in biological or non-ferrous metallic objects two-dimensional axisymmetric and three-dimensional Cartesian coordinates. The EC objects, magnetic flux density (MFD) space, (MF) of sensing coils are formulated state-space representation. harmonic responses electromotive force (EMF) coil closed-form solutions. proposed DCS is applied to design two systems. Bio-Differential Eddy Current (BD-EC) sensor distinguishes Metal-Coaxial (MC-EC) classifies objects. simulated field EMF numerically verified by comparing results with finite element analysis. An example utilized illustrate advantage calculating MFD, MF, contributed from ECD directly, generated each material. method, along prototype BD-EC sensor, has been experimentally evaluated on sweep frequency analysis detecting meat bone.

In this paper, a non-destructive eddy current test system was designed to evaluate the surface hardness of the carbonitrided steel parts. For this purpose, various samples of the tappet were used after the surface hardening and grinding operations as control samples and, if necessary, were subjected to destructive and non-destructive tests. Microstructural studies were performed with a microsco...
