Keywords: magnetosphere, ponderomotive force, magnetic field, protons, ions of helium, magnetic holes
Аnnotation: Ponderomotive effects due to electromagnetic ion cyclotron waves in the frequency band pulsations Pc 2 (0.1-0.2 Hz) in two-ion (proton and helium ) plasma is investigated. Near day boundaries of the magnetosphere in the presence of a certain density helium ions ponderomotive force leads to a significant increase in density of the background plasma in magnetic field minimum (magnetic hole), located symmetrically relative to the equator. When increasing the density of the helium ions is the increasing influence of ponderomotive forces on the change in the density of the background plasma.
