Observable Physical Effects during New Solar Active Regions Formations

Abstract

AbstractIn the present paper we are trying to demonstrate the importance of detailed observations for the theory of solar local magnetic field generation. Mutual relations of solar background magnetic fields and new active region formations are described. The influence of various factors, dependent as independent on the cycle of solar activity and the dynamics of background fields is considered. In the main chapter all forces and effects whose action can be derived from systematic observations of magnetic field distribution and high resolution photospheric photographs of all stages of active regions development are discussed. Before all the influence of convection, of the reaction on field lines penetration, of various magnetic forces, of differential rotation and of hydrodynamical forces is demonstrated. The importance of a „center of magnetic activity”︁ — a magnetic subsystem orthogonal to the main system of active region's field as a source of new magnetic flux is underlined. The necessity of a new approach to the problem of local magnetic field generation is stated.
