Figure: A cartoon and explication of the Earth's Van Allen belts
Image 1 Caption:
A very, very crude
cross section
diagram of the inner
magnetosphere
of the Earth
showing the Van Allen belts
(see also
Earth's magnetosphere).
Further explication:
- Some charged particles from the solar wind
do get trapped in reservoirs in the
magnetosphere.
These reservoirs are called the
Van Allen belts.
They are donut-shaped or toroidal and there are 3 of them
(PF-99): the inner 3rd belt
was discovered circa 2000.
The charged particles in the
Van Allen belts may
have other causes besides the solar wind.
- Note, since the image is a
cross section
diagram,
you have to envisage the
magnetic field lines
and Van Allen radiation belts
as having approximate
cylindrical symmetry
around the Earth's axis.
