Vector Potential of the Magnetic Field of an Overhead Ring Eddy Current Converter With Conductive Ferromagnetic Core

Defined vectorial potential of the magnetic field of the screened circular cylinder spool of rectangular transverse section with the current of arbitrary form which for the increase of sensitiveness and concentration of the magnetic field is placed on cylinder П-similar ferromagnetic to the core above the object of control in the form of leading ferromagnetic plate.
