Actually there are various levels of strata in the crust that exhibit
magnetically aligned elements, which first gave evidence that the poles
were not always in their current North-South configuration. However
all of these were either aligned with north as we know it or directly
opposite, (within some margin of 5-15 degrees I recall but can't state
as a definite fact) There were NO elements aligned in what are considered
east and west directions. Therefore the poles were hypothesized to have
shifted in a Geological nanosecond (probably no more than a year). Why
do they align on the rotational access? Who knows, but they seem to
only align in that way.
Random thought : What would it be like living in an equatorial area where
you were at the bottom of an electromagnetic funnel, as the north pole
is now?
