In this paper, I review most of the current knowledge about the strong correlation observed between the rotation rates and the magnetic fields of cool active stars. I concentrate in particular on the most recent observational results, derived from studies on dynamo field generation in stellar convective envelopes from magnetic imaging of very active rapidly rotating low mass stars. I also mention the latest attempts at investigating the large scale magnetospheric structure of these objects from extrapolations of the measured photospheric field maps, as well its dependence/influence on rotation. I finally discuss the new discovery of the feedback effects that dynamo magnetic fields generate on the global dynamics of stellar convective envelopes.
