[en] Hydromagnetic pulsations in the magnetosphere have been studied. The problem of their generation by the Kelvin-Helmholz instability has been solved in magneto-hydrodynamic approximation. Some experimental results are qualitatively explained. In the idealized case considered the plasma pause may serve as a source of long period pulsations. During the magnetic pause, short-period oscillations are generated
