The Sun is, by means of its closeness, the only star on which we can investigate spatially resolved surface and atmsopheric details. The dynamics of the solar atmosphere are caused by magnetic fields and the interaction between magnetic fields and the local plasma. It is of strong interest to investigate these dynamics also in the viewpoint of theoretical plasma physics and their application to fusion experiments.

In this talk we are dealing with small scale magnetic fields (in the range of 100´s of km and field strengths of about 1.3 kG) and their dynamics as seen by the Japanese/US/European Hinode satellite mission. This mission carries the largest up to now in space flown solar telescope with an aperture of 50 cm. We will give a short overview about the Sun and its magnetic field, about the topic of magnetic bright points (MBPs) and results gained so far.
