AbstractThe rnagnetic field of a circular-line current can be expressed (in complete elliptic integrals) so that there are no regions of mathematlcal failure or weakness. Such an expression is set up in spherical co-ordinates suitable to the study of ionospheric currents. It is shown that magnetic observations on the surface of the earth can then be used analytically to define current strength, height of current path, and curvature of current path. The analytical system is capable of development for coping with ribbon currents or more elaborate cases, though the present work does not extend beyond a selection of simple-line currents.
