Abstract

In this paper I give an overview of the numerous ways inwhich rotation and magnetic fields can interact under stellarinterior conditions.I first provide “tutorial”examples of how magnetic fields can (1) alter existing stellarinternal flows, (2) generate internal flows, and of how rotationcan (3) amplify or (4) destroy magnetic fields. The upshot of allthis is that treating rotation or magnetic fields in isolationof one another, as intermediate steps towards the “full picture”,may yield a situation that can only be applied meaningfully undervery limited and specific astrophysical circumstances, if any.
