The self-consistent description of magnetospheric dynamics requires careful analysis of magnetospheric plasma pressure and its distribution. Such analysis is relevant to the magnetospheric entropy problems, magnetospheric stability and solar wind control of magnetospheric dynamics. We summarize the latest finding of plasma pressure distribution at low altitudes and at the equatorial plane. We select a real changes produced by the approach based on the analysis of plasma pressure gradients in the analysis of high latitude magnetospheric processes. The configuration of large-scale transverse and field-aligned currents and mechanisms of their formation are discussed and analyzed. The role of magnetospheric current variations in the solution of outer radiation belt problem is discussed.
