The motion of particles in E-M fields, pitch angle evolution and an intro to the fluid description of a plasma
Topics of Particle motion in steady electromagnetic fields include:
Motion in uniform and non-uniform steady B fields - gyration, mirror motion, first adiabatic invariant.
E_|| is usually zero
Frozen in flow
Gradient and curvature drifts
Briefly, effect of collisions - Pedersen and Hall currents, loss cone
