Magnetic Fields of the Solar Atmosphere
The Sun is enveloped in a thick atmosphere which can be divided into the following three layers. As the lowest part, the photosphere has a thickness of only about 500 km. Above it is the chromosphere with a thickness of approximately 20,000 km. The outmost part is the corona, which has a scope of several to ten more solar radii. Its shape is not fixed and varies with the phase of the solar activity cycle. The magnetic field pervades the whole solar atmosphere and plays an important role in its structure, dynamics and evolution.
