Biermann battery mechanism and its role in evolution of astrophysical magnetic fields
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 influence of the existing magnetic fields (which can be induced by another charged particles) while studying the movement of the particles.
