Our motivation is modelling the interface region between solar photosphere and corona. We extrapolate Sunrise/IMaX photospheric magnetic field measurements upwards into the chromosphere and corona. A problem is that the interface layer is very complex. Relative importance of magnetic and plasma forces vary over several orders of magnitude. In the magneto-static approach the Lorentz-force is compensated by the plasma pressure gradient force and the gravity force.
