The north magnetic pole, also known as the magnetic north pole, is a point on the surface of Earth's Northern Hemisphere at which the planet's magnetic field points vertically downward (in other words, if a magnetic compass needle is allowed to rotate in three dimensions, it will point straight down).
Like the North Magnetic Pole, the North Geomagnetic Pole attracts the north pole of a bar magnet and so is in a physical sense actually a magnetic south pole. It is the center of the 'open' magnetic field lines which connect to the interplanetary magnetic field and provide a direct route for the solar wind to reach the ionosphere.
Scientists have been tracking the magnetic North Pole for centuries, telling the British newspaper The Times that it had moved closer to the northern coast of Canada. In the 1990s, it drifted into ...
A magnet's North pole is defined as the pole that is attracted by the Earth's North Magnetic Pole, in the arctic region, when the magnet is suspended so it can turn freely. Since opposite poles attract, the North Magnetic Pole of the Earth is really the south pole of its magnetic field (the place where the field is directed downward into the ...
In the past five years, the magnetic north pole has significantly slowed down to about 25km a year. The model assists in guiding a smartphone's compass tools. It also contributes to GPS systems ...
The geographic north pole doesn't move, and if we're putting things in the simplest of terms, it's the "top" of the globe. The magnetic poles, however, are constantly drifting.
Polar drift is a geological phenomenon caused by variations in the flow of molten iron in Earth's outer core, resulting in changes in the orientation of Earth's magnetic field, and hence the position of the magnetic north- and south poles. The North magnetic pole is approximately 965 kilometres (600 mi) from the geographic North Pole. The pole ...
The magnetic North Pole is moving so quickly that scientists are having to urgently update maps used for navigation systems, a report in science journal Nature said.
