moveing a wire though a magnetic field
The Earth's Magnetic North Pole, where the magnetic field lines become oriented vertically, moves constantly due to the drift in the Earth's magnetic field. In 2005, the Magnetic North Pole was located at 82.7°N by 114.4°W. To find the magnitudal 2-D land displacement (distance) from the Magnetic North Pole to the True North Pole, multiply the difference between the Magnetic North Pole's latitude (+82.7) and 90 degrees, by 60 nautical miles. (Or: [90-82.7 = 7.3] × 60 = 438 nautical miles). That value was correct for 2005, but keep in mind that any latitudinal shift in the position of the Magnetic North Poll indicates a change in distance between the two.
The idea that the Earth itself acts as a giant magnet was first proposed in 1600 by the English physician and natural philosopher, William Gilbert. He was also the first to define the North Magnetic Pole as the point where the Earth's magnetic field points vertically downwards. This is the definition used nowadays, though it would be several hundred years before the nature of the Earth's magnetic field was understood properly.

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.
