Perhaps this is off topic, but I was wondering if anyone else saw NOVA last
night. (11/18/03) The program was about the reversing of polarity of Earth
every few hundred thousand years. In the show, some of the scientists
referred to Earth as a dipole with a magnetic field that alternates.

Hi Alan,

And so?

Actually the program revealed through closer analysis that the earth
is a multipole (the anomalies) and that through the addition of all
poles (the anomalies) this creates an overall dipole behavior (when
interacted upon from space).

Much could be said of the standard halfwave antenna within/without the
near/far field regions.

Thats what the the Movie "The Core" was based on. If you believe the
movie, reversing of polarity could cause earth quakes, storms and the
shuttle to crash.
