It is found that thin magnetic tubes of radius about 107 - 108cm and longitudinal current 1011 - 1012A can be generated under the conditions of convective flows in the solar photosphere. Moreover, "magnetic holes", cylindrical magnetic structures with magnetic field decreasing towards the center, can be formed in divergent convective (Evershed) flows. It is shown that the steady-state Joule energy release (dissipation) at the photospheric footpoints of a magnetic tube increases towards the tube periphery in the upper photosphere and can exceed the optical radiation losses. In particular, this can lead to the occurrence of magnetic tubes with hot external envelopes. The authors consider two models of magnetic flaring loops in the active region. One model describes the explosive energy release in an individual loop caused by the penetration of the dense partially ionized plasma of a prominence into the magnetic tube (in the upper part of the loop) due to the flute instability or the penetration of the surrounding chromosphere plasma (in the chromospheric part of the loop). The second model of flaring energy release is based on the global approach in the study of the dynamics and energetics of solar active regions with allowance for their complex self-consistent evolution.
