Nowadays it is well-known that a wide range of astrophysical objects have large-scale magnetic fields. Their observations are usually carried using Faraday rotation measurements. One of the possible mechanisms of their generation (at least the seed ones) can be connected with the Biermann battery mechanism. It is connected with difference between masses of protons and electrons, which are interacting with the cosmic medium. They produce the circular currents which can be generate the magnetic field which is perpendicular to the rotation plane. Here we present the mechanism of the magnetic field generation by the Biermann mechanism in the disc objects which can be useful for galaxies, accretion discs and another objects. One of the important features is connected with the in uence of the existing magnetic fields (which can be induced by another charged particles) while studying the movement of the particles.

Communications of the Byurakan Astrophysical Observatory (ComBAO) is a peer-reviewed scientific journal, which publishes research in observational and theoretical astronomy/astrophysics and presents recent advances in these fields. It is being published by the NAS RA V. Ambartsumian Byurakan Astrophysical Observatory (BAO) in English in electronic form. The journal publishes original papers, review papers, brief reports, book reviews, special communications, observational and theoretical results in various fields of astronomy and related sciences, and some editorial notes, including anniversaries and obituaries. Under the heading “Legacy”, the renewed magazine will republish some old articles of high value in English. The heading “Guest articles” will bring to the attention of readers the articles of researchers who are not employees of BAO. ComBAO was founded in 1946 and regularly published in 1946-1990. However, the publication was interrupted because of the economic situation after the disintegration of the Soviet Union in 1991.
