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.
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).
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.
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.
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.
The direction of the field determines whether the pole is a magnetic north or south pole, exactly as on Earth. The Earth's magnetic axis is approximately aligned with its rotational axis, meaning that the geomagnetic poles are relatively close to the geographic poles. However, this is not necessarily the case for other planets; the magnetic ...
Earth's magnetic field is what protects our planet from harmful space radiation. ... Over the past 150 years, the magnetic North Pole has casually wandered 685 miles across northern Canada. But ...
In 2014, a magnetic field around HD 209458 b was inferred from the way hydrogen was evaporating from the planet. [20] [21] In 2019, the strength of the surface magnetic fields of 4 hot Jupiters were estimated and ranged between 20 and 120 gauss compared to Jupiter's surface magnetic field of 4.3 gauss.
