- Аннотация: The question on a role of the electric currents distributed over the volume of active regions is considered from the point of view of the solar flare physics. It is suggested to include the electric currents in a topological model of magnetic field in an active region. With application to the M7/1N flare on 27 April 2006, there are obtained the estimates of characteristic values of the mutual induction coefficient and the energy of interaction of the coronal electric currents flowing along magnetic-field loops. It is shown that, if the currents do contribute significant energy to the flare, then they should be observable in the photospheric magnetic fields. Depending on orientation of distributed currents, they help or hinder reconnection in a current layer at a separator during the flare. Asymmetric reconnection of the current is accompanied by their interruption and an inductive change of energy. Reconnection of currents in flares significantly differs from the ordinary instability of coalescence of magnetic islands in current layers. In order to investigate quantitatively the role of distributed currents in solar flares, there are needed the high accuracy measurements of magnetic field in active regions.
