The earth's magnetic field protects us from cosmic rays, which
are extremely high energy subatomic particles generated by esoteric
processes in interesting parts of the universe. To get an idea of
how this protection might happen, pretend the earth's magnetic
field has a constant value of 5.0 x 10^-5 T (northward) from the
ground to a height of 50 km.
