I added the ability to simulate a charged particle moving in the Earth's
magnetic field to my simulator.   This lets you look at the motion of
particles in the Van Allen Belts.  

The particles move fast.  In the samples I created I have protons going
nearly 1/3 the speed of light.  They spiral around a North/South magnetic
field line very quickly.  A bit less quickly they are moving north and
south (up and down).  And much less quickly they are drifting East around 
the world.

This is a very 3D motion, so my samples look first from the side (so you
can see the North/South motion) and then from the top (so you can see
circles and movement around Earth).

Java applet is at http://spacetethers.com/spacetethers.html

The samples are #85 to #88.
