Some time ago JS woundered why we view the center of the earth is not
represented by force vectors
pushing OUT ie the equal and opposite reaction with respect to
gravity. This is a very insightful comment.
In fact the earth's ferrite mass center is represented by the magnetic
poles but because of the diagmagnetic content of the earth which
produces a weak magnetic field at right angles to a ferrite field we
have two magnetic axis at a distance from each other in our earth and
not just one.Thus somewhere, in between these two pole structures, we
have a point of equilibrium where the vector forces emminate from this
point in a outward direction. It is the position of the diagmatic pole
that provides the "curl" effect as seen when studying the radiator
vector format which is also responsible for the earth turning and the
circular rotation of a pendulum to which a radiator is often compared..
( By another name I believe this also describes the Corriolis effect)
One can stretch their minds and ponder on the effect of this
diamagnetic pole tho weak would have on a compass on opposite sides of
the earth, such as the Bermuda triangle and the area on the other side
of the earth but of to the side where Amelia Erhardt altered her
course for a unknown reason and disappeared.
