Magnetic field data measured during numerous planetary missions in the last four decades have revealed a large diversity in planetary magnetism and dynamos. Some planets generate a present day magnetic field in their metallic cores while others do not and/or some have a remanent magnetized crust indicating for instance the existence of an early self-generated magnetic field. The study of intrinsic relations between the internal magnetic field and the dynamics of a planet is viewed as a cross-disciplinary effort to provide insights on the formation, composition and evolution of a planet. This session is aimed to papers discussing new magnetic field data, dynamo and magnetic field models, planetary dynamo generation, core-mantle thermal coupling and planetary dynamo efficiency, and control of core-mantle heat flow pattern on magnetic field generation. Contributions that discuss the implications of new high pressure experiments and theory for the state of the core and dynamo operation are also encouraged, as well as studies investigating magnetic anomalies and their implication to dynamos and planetary evolution.
