Summary

Large-scale electric fields exist in the magnetosphere, capable of convecting the low-energy plasma that exists there and perturbing the trajectories of the high-energy particles. Both the plasma and the particles undergo energy changes as a result. These changes may be described hydromagnetically, with the aid of thermodynamic concepts, or on the basis of particle-drift theory. The present paper demonstrates that these two approaches are quite equivalent on the differential scale, and that some degree of equivalence can be maintained on the integral scale.
