Abstract
The problem solved is that of electromagnetic induction in a thin non-uniformly conducting hemispherical shell underlain by, and insulated from, a perfectly conducting sphere. Since the shell is assumed thin, only the component of a varying magnetic field normal to the shell induces electric current in the shell. This mode of induction is termed vertical component induction. The conductance and configuration of the surface shell are simple approximations to those of the Pacific Ocean. Calculations are made of the effect of induction by the Sq variation field and results are presented for typical “land” and “ocean” regions, and for a profile of stations near the ocean edge. The results from this profile of stations are compared to observations made by SCHMUCKER (1970) near the coast of California. The calculated and observed daily variations of the vertical component of the magnetic field are in qualitative agreement.
