Popis:	The strong magnetic fields of active regions organize both the plasma structures and energy processes in the chromosphere and corona. Recent radio observations with high spatial resolution permit measurements of the magnetic fields in these regions and also localize regions of thermal and nonthermal energy release. They can additionally be used to determine temperatures and electron densities in these regions. The results of such diagnostics suggest the term magnetosphere for the space surrounding an active region in the solar atmosphere where the basic structures and physical processes are controlled by the magnetic fields/electric currents of the particular region
