Abstract

THE discovery of an intrinsic magnetic field for the planet Mercury by Mariner 10 (ref. 1) and its preferred source in an internal dynamo2 imply the existence of a conducting molten core. We propose here a feasible, non-seismic observational experiment to determine the existence and extent of such a molten core, which would be vital for calculations of Mercurian thermal histories and dynamo field generation.
