Fig.12. Electron beam injected into a nonuniform magnetic field
with a null line. The beam meanders along a magnetic null line
pointing diagonally down to the right. Note the reversal of the
cyclotron rotation as the magnetic field reverses to either side
of the neutral line. Such meandering and figure-eight
trajectories have been studied theoretically in the problem of
magnetic reconnection occuring in the magnetosphere and on the
sun.
