Abstract: |
We suggest a mechanism of formation and amplification of magnetic fields in the central fast rotating region of active galaxies, when exists an outflow or inflow of ionized matter from or on the central part. Because of the large differences between the time of scattering of electrons and protons of expanding or collapsing matter with the particles of rotating medium, in every point of rotating medium the rotation velocity of scattered electrons and protons will be different and correspond to the rotation velocity of their last scattering point. In the result of this difference are forming circular electric currents in the central part of Active galaxies, and forms dipolar magnetic fields. If the process of outflow or inflow continues sufficiently long time the equipartition of magnetic and rotational energy of the central part of the galaxy will be reached. Observed large amount of fast rotating matter in the central region and the existence of outflow or inflow of plasma in active galaxies provide a good condition for the working of suggested mechanism. |
