Abstract: Electromagnetic (EM) sounding of planetary bodies other than the Earth was first possible on the Moon, but has since been used to probe interior structure of planets and moons throughout the solar system. This emergence has been facilitated by the growing availability of mission data and associated improved understanding of planetary magnetic field environments. In this review, I outline the general principles of EM induction, with particular emphasis on planetary specific assumptions and aspects that have to be considered in non-terrestrial environments, including limited or incomplete datasets. I review magnetic field mission data from past and ongoing space missions that can support EM investigations. The availability and quality of such data determine the scope and depth of investigations, ranging from characterizing most interior layers to identifying subsurface oceans. Looking ahead, upcoming missions will facilitate a better characterization of planetary bodies, which will contribute to addressing most fundamental questions, including the possibility of oceans and potential for life within the Jovian system.
