  Continuous high-precision photometry of stars, provided by space missions
such as CoRoT, Kepler, and K2, represents a unique way to study stellar
rotation and magnetism. The coupling of these studies of the surface dynamics
with asteroseismology is changing our view to surface and internal dynamics. In
this proceedings I will provide the latest developments in the understanding of
surface and internal rotation and magnetic fields. I will also discuss the
possible discovery of strong internal magnetic fields of dynamo origin in the
convective cores of stars above 1.2-1.4 solar masses. I will finish by
providing constraints on gyrochronology laws for low-mass stars and put the Sun
into context of its magnetism when compared to other solar-analog stars.
