The Sun is a fascinating astronomical object. If unmagnetised it would probably be a quite boring star, but the interplay between the solar plasma and the magnetic fields make the Sun a unique laboratory for testing theories of magnetised astrophysical plasmas. Because of its proximity, we have access to physical phenomena occurring at scales as small as the limits of current instrumentation, i.e., as small ~100 km. Stars bring the opportunity to understand how some activity phenomena observed in the Sun can be excited or inhibited in other situations. In this talk, I will summarise my research work on both solar and stellar magnetism studies, emphasising the solar-stellar connection. This work comprises the quiet Sun magnetism, or the more chaotic, disorganised and small-scale magnetism ever observed in a star, to the most fascinating, large-scale manifestations of magnetic fields: solar and stellar prominences.
