Investigations on the numerical calculation of the force-free magnetic field for solar active regions and its application, carried out by the author and his collaborators in recent years, is summarized. In this paper, some existing numerical calculations of constant a force-free fields for active re
The problem of the accumulation and storage of the energy released in solar flares is discussed; it is propose d that convective energy of the photosphere is transformed into magnetic energy of the chromosphere and corona. The consequences of a large ratio of magnetic pressure to gas pressure are in

Numerical calculations of two-dimensional force-free fields as models of solar active regions are presented. For a given 'toroidal' component of the photospheric magnetic field two branches of solutions are numerically obtained which merge at the critical point of maximum allowed toroidal magnetic f
