t is known that Earth’s magnetic field has flipped many times throughout the planet’s history. Its dipole magnetic field remains about the same intensity for thousands to millions of years, but for incompletely known reasons it occasionally weakens (such is the case now) and, presumably over a few thousand years, reverses direction. A new study, however, shows that the final stage - a sudden 180-degree flip - can happen within a human lifetime.

 The new study was done by a team of scientists from Italy, France and USA and it demonstrates that the last magnetic reversal of Earth's poles which happened some 786 000 years ago actually happened very quickly, in less than 100 years.

Wonder how much money the greenies with make stopping this from happening
Good God hockey being played and at the equator. I hope it flips the right way
and a certain middle area of the world will be in Antarctica wouldn't that solve a
few problems

Really? Hockey at the equator? Oh, that's right, you were a radio personality. That explains a lot. Don't have to be all that intelligent for that job, just be able to talk a lot.


We are talking about the "MAGNETIC" pole, not the north and south poles. The "magnetic north pole", at this time, is sitting somewhere around.......




Located hundred of miles south of the geographic North Pole lies the magnetic North Pole at approximately 82.7° North and 114.4° West (2005), northwest of Canada's Sverdrup Island. However, this location is not fixed and is moving continually, even on a daily basis.

The earth's magnetic pole is the focus of the planet's magnetic field and is the point that traditional magnetic compasses point toward. Compasses are also subject to magnetic declination which is a result of the earth's varied magnetic field. Each year, the magnetic North Pole and the magnetic field shift, requiring those using magnetic compasses for navigation to be keenly aware of the difference between magnetic north and true north. The magnetic pole was first determined in 1831, hundreds of miles from its present location.


The National Geomagnetic Program of Geological Survey of Canada monitors the movement of the north magnetic pole and most recently determined its precise location in a 2001 survey. They've determined that the pole is moving at approximately 25 miles (40 kilometers) each year.
The north magnetic pole moves on a daily basis, too. Every day, there's an elliptical movement of the magnetic pole about 50 miles (80 kilometers) from its average center point.

Moving 800x faster than normal and 20% weaker than normal.

could this polarity reversal of earth cause earth to rotate suddenly? :shock:

In the bush near Sudbury
I can't really imagine the Skil will run backward or anything like that. Theoretically, the Earth's magnetic field changes relative to the equipment every time it's moved. Now, if you're out in the bush with only a compass for guidance, you may be advised to take a ball of string
