The y and z components have simple harmonic solution, which can be
written as
vv Gt
yz
(6.2)
where G and H are arbitrary constants and
c
qBm
0
Thus, in the y–z
plane, the particle describes a circular motion at the cyclotron frequency.
The guiding center drifts in the x direction, and the drift is oscillatory. The
charge-dependent drift is opposite for electrons and ions. This motion of the
charge particles helps plasma connement because as the particles drift in
the x direction they are caught in the magnetic eld lines.
