摘要

如今,众所周知,许多天体都有大规模的磁场。他们的观测通常使用法拉第旋转测量。它们产生的一种可能机制(至少是种子机制)可以与比尔曼电池机制联系起来。它与质子和电子之间的质量差有关,质子和电子与宇宙介质相互作用。它们产生圆形电流,圆形电流可以产生垂直于旋转平面的磁场。本文给出了盘状天体中由比尔曼机制产生磁场的机理,对星系、吸积盘和其他天体的研究有一定的参考价值。在研究粒子运动时,其中一个重要特征与现有磁场(可由另一个带电粒子诱导)的影响有关。

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.
