Based on magnetic fields frozen into old lava fields, during a magnetic pole flip, first the major poles get weaker and weaker and the subpoles (such as the South Atlantic Anomaly) become real poles. During this period there might be four, six or even more local poles, so navigating with a magnetic compass would be a challenge, especially when these poles may move with a considerable speed, making paper maps obsolete quite quickly :-). During this period, Aurora Equatorialis might be observed, when the solar wind hits the atmosphere close to the local pole. Finally, the flipped main poles get much stronger than the subpoles, so the minor poles are just magnetic anomalies.

I 'discovered' this when I was trying to use a compass match up sets of Helmholtz coils. Drove me 'nuts' for a day or so. George H.

The Earth's magnetic field acts like an invisible protective shield that "steers" the solar wind -- and the high energy particles contained therein -- around and away from the surface. During a reversal, the position and intensity of this "shield" will change. It is possible that during this change, the Earth -- and the critters living on it -- may be subjected to anything from inconvenient levels of radition to life-threatening and/or mutation-inducing doses. The reason that I bring this up is that there appears to be an uncomfortably close relationship between previous "flips" and hitherto-unexplained mass-extinctions and the subsequent emergance of entirely new species. Everyone (except Al Gore) understands that correlation between events is not the same as causality. But there seem to be enough multiple-event correlation to suggest a causal relationship. Sorry to mess up the holidays with this. BTW, some folks think we are already overdue for the next flip. :-) Bill Miller

Wondering... perhaps... could it coincide with our solar system (and us) passing from one side of the galactic equator to the other? Even the lunacy of folks like Gore, and the 'scientists' that gave him the peace prize might well be attributable to the approaching 'event' having an affect on some folks' minds. If it is controlled by our position within the galaxy itself, we are essentially screwed. Nothing will be the same, regardless of whether you stereo actually works or not. |
