Abstract

The second-order approximation in a quasiparticle description of magnetized plasmas is studied. The second-order adiabatic invariant of quasiparticle motion is found. Global adiabatic invariants for a magnetized plasma are revealed, and their possible role in energy exchange between particles and fields, nonlinear mode cascades and global plasma stability is discussed.
