Concepts of gravitational and electromagnetic structures of astrophysical objects are introduced. The two structures have different properties and stationary states. In some cases the electromagnetic structure appears to be dominating. Relativistic jet is a typical attribute of electromagnetic structure. In particular, high degree of the jet collimation is explained freely as a phenomenon of the electromagnetic structure, and hardly can be explained in terms of magnetohydrodynamics. Interaction between the gravitational and electromegnetic structures is considered and estimated.
