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.
In 2013, the distance between the north magnetic pole and the geographic north pole was approximately 800 kilometres (500 mi). [8] As of 2021, the pole is projected to have moved beyond the Canadian Arctic to 86°24′00″N 156°47′10″E / 86.400°N 156.786°E / 86.400; 156.786 ( Magnetic North Pole 2021
Magnetic declination varies both from place to place and with the passage of time. As a traveller cruises the east coast of the United States, for example, the declination varies from 16 degrees west in Maine, to 6 in Florida, to 0 degrees in Louisiana, to 4 degrees east in Texas.
British explorer Sir James Clark Ross discovered the magnetic north pole in 1831 in northern Canada, approximately 1,000 miles (1,609 kilometers) south of the true North Pole. We now know that ...
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 ...
Now, NASA has released a 3D infrared movie of Jupiter's north polar region, depicting the intense storms in the area, as well as the dynamo that powers the planet's massive magnetic field.
As with Earth's, Jupiter's magnetic field is mostly a dipole, with north and south magnetic poles at the ends of a single magnetic axis. [2] On Jupiter the north pole of the dipole (where magnetic field lines point radially outward) is located in the planet's northern hemisphere and the south pole of the dipole lies in its southern hemisphere.
Planetary magnetic poles are defined analogously to the Earth's North and South magnetic poles: they are the locations on the planet's surface at which the planet's magnetic field lines are vertical. The direction of the field determines whether the pole is a magnetic north or south pole, exactly as on Earth.
