The formula for the change in impedance of a single-turn coil located inside a cylindrical region with varying electric conductivity and magnetic permeability is derived in the present paper. It is assumed that the electric conductivity and magnetic permeability of the conducting medium depend on the radial coordinate. The solution is expressed in terms of improper integrals containing Bessel’s functions of complex argument. Results of numerical calculations are presented.
