The outer hot and dynamic atmosphere of the Sun, the corona, is dominated by the magnetic field. Convective motions near the surface are braiding the magnetic field lines that reach into the corona, and by this induce currents which are then dissipated and heat the plasma. Numerical experiments can capture the underlying processes well enough to reproduce the complex observations of the real Sun. The interplay of modern solar observations and numerical models on supercomputers provides the means to get closer to an understanding of the heating, structure, and dynamics of the solar corona.
