Abstract : The general solution for the field due to a currentbearing circular loop near an oblate spheroid has been derived. The constitutive parameters, sigma sub 1, mu sub 1, epsilon sub 1, of the material composing the spheroid may have arbitrary values. However, since to evaluate this case numerically entails considerable difficulties, the quasistationary case involving a perfectly conducting spheroid was used. This case was further specialized by making the spheroid infinitely thin; that is a thin circular disk was obtained. For this special case, graphs were made of the magnetic lines of force, which illustrate their dependence on disk radius and separation of loop and disk. Also graphs are given for obtaining the flux for different circular crosssections in the plane of the loop. (Author)
