Study on the Earth magnetosphere according to the investigation results of charged particle flows

Data on spatial distribution of solar cosmic ray fluxes in a magnetosphere are analysed. The position of polar cap and plasma layer boundary is determind. Interrelation between change in the structure of these fluxes with a solar wind pressure and the value and direction of interplanetary magnetic field is detected. The structure of high-latitude fluxes of electrons of a magnetospheric origin is compared with model representations about the character of particle motion in the magnetosphere
