Abstract
Activity on the Sun is associated with magnetic fields, involving a complex interaction between the field and plasma. In this review I focus on three fundamental aspects of magnetic activity: (a) the generation, storage and emergence of magnetic fields from the solar interior; (b) the nature of the surface magnetic fields, especially in the form of small-scale flux tubes; and (c) dynamical processes in flux tubes and heating of the magnetic chromosphere.
