Numerical Test of Kelvin's Phase Approximation in Calculating the Magnetic Field of an Elemental Ring of Meridional Currents on a Sphere,

Abstract

An integral expression is derived for the surface magnetic field produced by a ring of meridional currents on a perfectly conducting sphere. This expression is approximated via Kelvin's stationary phase principle, and numerically compared with an evaluation of the integral via Chebyshev's Quadratures. The results have implications for the prediction of LORAN navigation coordinates. (Author)
