Earth’s Magnetic North Pole Drifting Towards Russia…   Leave a comment

[January 8, 2011] The airport in Tampa, Florida, has had to temporarily close its runways to keep up with Earth’s magnetic north pole, which is drifting toward Russia at a rate of 65 kilometers per year.

The international airport was forced to adjust the signs on its busiest runway Thursday because pilots depend on the magnetic fields to navigate.

The runway will be closed until Jan. 13, and will re-open with new taxiway signs that indicate its new location on aviation charts.

Earth’s magnetic field is thought to be generated deep inside the planet. Scientists believe that an inner core of solid iron is surrounded by an outer core of molten iron.

They rotate at different rates, and the interaction between the regions creates a ‘hydromagnetic dynamo,’ acting something like an electric motor, and it generates a magnetic field akin to a giant bar magnet.
