The mag. "flip" or reversal is an intersting scenario, how does it work....not sure...but supposing it is not instantanious and it also goes through zero in the process of "fliping" that begs the question of....no magnetosphere, yes Kentucky fried chicken at twenty paces, I don't think a mine would help unless you go down Western Deep followed by a load of mass concrete, same end game really.

I think you will find it isn't expected to switch off and then on again the other way round - it is expected to wander slowly from one end the other, so at some stage the north pole might be in the middle of the Amazon basin. I think that where the effect of the magnetic field has been "fossilised" or recorded in some way in the rocks, this is just the sort of thing that has been detected. If the magnetic field is still there, but not as we have it now, why should the magnetosphere not continue to work? I imagine the aurora might be visible at some very odd places while it is happening.

Hello Peter, mag reversal is something I know liitle about including any proccesses that might be involved, wasn't it noticed somewhere in the rocks of the Great Atlantic Ridge ? I would think it's all still in the stages of "the black art" the point I was making was that if during any mag process it was to collapse through zero flux line or part collapse from it's present form for any reasonable period then the consequences would be rather severe, even more severe if what ever reason it did not recover, getting back to the OP's originall post and EMP, maybe daft, maybe not, if any sudden (fast) reduction of mag strength were ever to occur then the laws of physics (that great catch all) will come into play.
A rapidly collapsing mag flux on an earth scale would be seriously bad news, BEMF, undamped peaks etc, the mind boggles.
However if some kind of pole shift were to occur then I hope it settles in Scotland and I will be able to see the Northern Lights from my back garden, very nice.

I wasn’t aware of that Pete; I thought it was a straight reversal.

The study of ocean ridges helped explain this. The spreading of the ocean crust creates tears and cracks in the crust into which the magma from below intrudes. As this magma cools and solidifies, a record of the earth’s magnetic field becomes frozen in the rock. Millions of years later as it moves further from the ridge it still carries this record. It was discovered that the pattern left behind by the magnetization sometimes reversed

This curious pattern was explained by the discovery that the Earth's magnetic field undergoes intermittent field reversals. That is, the magnetic field points northward for awhile, then southward for awhile, then northward again, and so on. As each region of the sea floor was forming at the ridge axis, it froze into the solidifying magma a record of the Earth's magnetic field at that time, and then carried this record outward with it as it moved away from the ridge axis. Since the sea floor spreads in both directions from the ridge axis, the pattern is symmetrical across the ridge.

Verification that the Earth's magnetic field reverses direction came from studies of the magnetism in both ancient lava flows and ancient sedimentary deposits. These studies confirm that the field reversals occur at irregular intervals, and a period of one dominant polarity (i.e., north or south) typically lasts between several hundred thousand and a million years.

The magnetosphere will continue to work because it's made up of only electrons (negative) and protons (positive) derived from the solar wind - a plasma of electrically conducting gas.

How does that relate to Greenwich Mean Time? Is it x hours in front or x hours behind?

My concern is that the lines of latitude invented by an unknown Greek many centuries ago are going to get broken as the poles move about. Nobody has maintained them in living memory so they are probably quite weak - mainly due to global warming. We need to get a team of knot experts together quickly to mend them. If we can make them strong enough it might help to keep the poles in place and we need not worry about pole reversal. After all, the last magnetic reversal was before the invention of lines of latitude, so there was nothing in place to prevent it happening.

Thanks carnkie, yes that's what I heard, the Atlantic Ridge etc.
The magnetosphere is dependant on the earths mag field, it can be distorted/shaped by solar wind etc and penetrated.
A suddenly collapsing mag field has consequences, as to wether this has ever or will happen to the earths mag field is another matter, I guess a powerful enough external force/energy could do it no problem even by maybe by some kind of absorbtion, oh dear the earths core temp might change.

S'gunna be a bit of a mess at the poles, and, we're going to need a LOT of string. I wonder if Mr Darkplaces has kept all the string from Box, it might just be enough!!

Yes, I think it was this year that the end of the world was scheduled, but what with the Olympics and the weather and all that. Cant really blame the organisers.

Yes! Have always thought Cwmorthin slate mine would be a superb venue for a staging of Richard Wagner's great music drama "Der Ring des Nibelungen" which culminates in the end of the world! Smartass Blink Laugh Laugh

Is your friend David Icke perchance ?

Can he not just pop them in an orgone accumulator or something to keep them safe ?

It great that he's going to save something for when people like me get wiped out, after all he managed to save sod all for Hereford United.

Yes, that's what I was infering in some of my posts, don't worry though the US HAARP Project is doing plenty of research......
I suspect the Soviet Woodpecker might have done some damage at the time, it certainly wiped out half the SW Radio spectrum when it was in full pelt.
