What is Earths magnetic pole?

The Earth's magnetic north pole is a point at the top of the northern hemisphere where the magnetic pull is straight down, toward the Earth's core. It is not the same as the Earth's geographic north pole. The geographic north pole is fixed at geodetic latitude 90° North. However, the magnetic north pole drifts, based on magnetic changes to the Earth's core. Some scientists think it is drifting toward Siberia 34-37 miles (55-60 km) per year, and can vary from day-to-day up to 50 miles (80 km) per day, because of the Earth's elliptical movement.

Here are some measurements of the location of the Earth's magnetic pole:

In 1831 = 70°5.3'N 96°46.0'W

In 1904 = 70°31'N 96°34'W

In 1930 = 72.3°N 98.7°W

In 1994 = 78.3°N 104.0°W?

In 2001 = 81.3°N 110.8°W?

In 2005 = 82.7°N 114.4°W?

In 2007 = 83.95°N 120.72°W

In 2010 = 85.0°N 132.6°W

In 2011 = 85.1°N 134.0°W

The pole wanders daily in a roughly elliptical path around this average position, and may frequently be as much as 80 kilometers away from this position when the Earth's magnetic field is disturbed.
