The role of large-scale magnetic field in the morphology and evolution of extragalactic radio sources

We discuss a model of formation of extragalactic radio sources when the parent optical galaxy has a large-scale dipolar magnetic field. The study of dynamics of ejected from the central part of optical galaxy clouds of relativistic particles in dipolar magnetic field gives a possibility to explain main morphological features and physical properties of formed extragalactic radio sources. We bring some results of statistical analyses and correlations between physical parameters for more than 500 radio sources. In appendix we present the data of all used extragalactic radio sources with the references for them.
