Abstract

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