The spacecraft verified the existence of a magnetic field surrounding the planet and discovered that the field was offset from the centre and tilted in a manner similar to the field around Uranus. Neptune's rotation period was determined using measurements of radio emissions and Voyager 2 showed that Neptune had a surprisingly active weather ...
The induced moment is directed radially to or from Jupiter following the direction of the varying part of the planetary magnetic field. The induced magnetic moment is an order of magnitude weaker than the intrinsic one. The field strength of the induced field at the magnetic equator is about 60 nT—half of that of the ambient Jovian field. [23]
SGR 1806−20 is a magnetar, a type of neutron star with a very powerful magnetic field, that was discovered in 1979 and identified as a soft gamma repeater.SGR 1806−20 is located about 13 kiloparsecs (42,000 light-years) [1] from Earth on the far side of the Milky Way in the constellation of Sagittarius.
As the largest planet in our solar system, Jupiter has a magnetic field 20,000 times stronger than Earth’s, according to NASA. The magnetic field traps charged particles and accelerates them to ...
These magnetic fields are a hundred million times stronger than any man-made magnet, [11] and about a trillion times more powerful than the field surrounding Earth. [12] Earth has a geomagnetic field of 30–60 microteslas, and a neodymium-based, rare-earth magnet has a field of about 1.25 tesla, with a magnetic energy density of 4.0 × 10 5 J ...
Jupiter's magnetic field is the strongest of any planet in the Solar System, [102] with a dipole moment of 4.170 gauss (0.4170 mT) that is tilted at an angle of 10.31° to the pole of rotation. The surface magnetic field strength varies from 2 gauss (0.20 mT) up to 20 gauss (2.0 mT). [ 123 ]
The findings suggest why there could be such a stark difference between the planet’s northern and southern hemispheres: erosion caused by water 4 billion to 3.8 billion years ago.
