An approximate analytical method is presented for treating electromagnetic scattering from a slender cylindrical conductor buried in a homogeneous conducting half‐space. The excitation is by a uniform line source of current located on the surface. The solution is achieved by an iterative method that accounts for the interaction of the induced current in the cylinder and the air‐earth interface. It is shown that the cylindrical inhomogeneity will distort the profile of the subsurface magnetic field as the horizontal displacement is varied.
