On Earth Changes Media Site, Mitch Battros has a post talking about the pole reversal. In this piece he says that the earth’s iron core causes earth to act like a giant magnet which acts in a bipolar way that isn’t permanent and varies due to the liquid core. He also says that science has proven that the poles have reversed in the past and that there is a magnetic anomaly in the southern hemisphere that was picked up in a study done by a Geophysical Institute in France. There seems to be a “dip” in our magnetosphere called the South Atlantic magnetic anomaly (SAMA).The picture didn't stay in but you can see a world map with the anomoly's location at the link below.

You can read the first paragraph of his post (I haven’t included it here) with anomoly's location in the world picture, even if you are not a paid member of his site.

I paraphrased as best as I could from the second paragraph through to and including the fifth paragraph here and then copied about 1/3 of his original post that non-subscribers cannot access below.

Click on this link and scroll down to “The South Atlantic anomaly and Charged Particles” to see 1st paragraph and picture.

He doesn’t answer the question at the end (last sentence below).

The minimum value, of the total geomagnetic field F of about 22,850 nT is found around 26° South and 54° West, which agrees well with the International Geomagnetic Reference Field (IGRF) model for the year 2000. The F field strength within the radius of about 1000 km around the F minimum point is less than 23,000 nT. It can be noted that the anomaly is dynamic, the center of the anomaly, that is the area of F minimum, has traveled in the last century from near Rio de Janeiro (23°.0 S, 43°.0 W) to Rio Grande do Sul (29°.0 S, 54°.0 W).

These locations are determined from a combination of the magnetic maps prepared by the Brazilian National Observatory, Ministry of Science and Technology, Rio de Janeiro and the IGRF models Marins (2002). The center of F minimum and location of magnetic equator both have undergone a large secular variation unseen elsewhere. It is thought that this westward drift of the center of the anomaly and magnetic equator may be related to the westward drift of the geomagnetic axis of the Earth. The present value of F at São Martinho da Serra (SMS) (29°.43 S, 53°.80 W) is 22,883 nT and it is decreasing at the rate of 28 nT/year.

If the South Atlantic magnetic anomaly (SAMA) is taken as signal of an imminent reversal of our planet´s magnetic poles, how imminent is the reversal occurrence?
