## Equation of Density of Calculation Currents of Vector Potential of the Magnetic Field of an Overhead Ring Eddy Current Converter With Conductive Ferromagnetic Core

On the basis of opening of boundary conditions the got equalizations are for determination of density of calculation currents in case of analytical calculation of vectorial potential of magnetic-field of the superimposed circular eddy current converter with electric conduction ferromagnetic core above the object of control in form a leading ferromagnetic plate.
