Abstract
The problem of the origin of planetary magnetism is formulated as a bifurcation problem and some recent theoretical work on the generation of magnetic fields by buoyancy-driven convection in rotating spherical shells is briefly reviewed. Since the lack of laboratory experiments has hampered the theoretical progress, a possible configuration for a laboratory apparatus is proposed.
