They went to the south pole, holding a compass that worked everywhere else, and wathced as it spun around at high speeds.
That doesn't actually work, since the south and north poles aren't at the magnetic centre.
Besides, that just backs up the FET since they hypothesise that all magnets point to the centre of the earth laterally. Compasses point to the edge. Get near enough to the edge and the direction towards the edge obviously becomes less distinctive.
However, that raises an interesting point. I'd like to know how the FE'ers would like to explain the movement of the magnetic poles (i.e. the FE "centre" is moving, and has been moving more rapidly of late, and according to geological records it will reverse polarity every few thousand years, seemingly at random).
Here's the RE explanation. I think the most striking thing is that they can use a computer to simulate this event successfully, based on RE theories alone.
Would this simulation even be possible if the FET was correct? Is even basic physics capable of explaining FET?
