In many space plasma systems, especially when the magnetic field is weak, characteristic scales of the inhomogeneities of the magnetic field are much smaller than the Larmor radius of the ions. Over the last two decades there has been active development of quasiadiabatic models of the dynamics of charged particle in such systems. In this paper, we systematically review the quasiadiabatic approximation and illustrate how it can be used to describe various phenomena in the Earth magnetosphere and to explain many effects observed by satellites.
