In this presentation I will discuss how a dynamo can be driven in the thin stably-stratified atmosphere of a hot Jupiter. This dynamo is driven by horizontal conductivity variations arising from the constant day-night temperature differential. While the hot Jupiter case is extreme, due to its strong asymmetry, its possible a variable conductivity could lead to interesting, unexplored dynamics in other MHD systems.
