A model of a device for nondestructive control by eddy currents has been proposed. The device and the object under control are represented by an equivalent circuit in the form of an electromagnetic circuit described by the system of differential finite equations in the coordinates of loop magnetic fluxes and currents of windings. The model allows us to take into account three parameters of the defects: depth, width, and conductivity. The spline method of analysis of periodic processes is used to carry out calculation.
