DEPENDENCE OF REFLECTED IMPEDANCE ON THE SPEED OF THE RELATIVE MOVEMENT OF THE COIL AND CONDUCTING HALF-SPACE IN EDDY CURRENT MEASUREMENTS

DOI: 10.17804/2410-9908.2015.5.016-021

Graphic dependences of real and imaginary components of the impedance introduced into the coil on the coil movement speed are constructed. The pictures allow us to estimate the possibilities of eddy current control at high speed of the movement.

Keywords: eddy current, NDT method, computer modeling
