2025年1月27日 · Like the other giant planets, Uranus has a magnetic field that is generated by convection currents in an electrically conducting interior. The dipole field, which resembles the field of a small but intense bar magnet, has a strength of 0.23 gauss in its equatorial plane at a distance of one Uranian equatorial radius from the centre.

2024年12月31日 · Uranus has auroras, but they are not in line with the poles like they are on Earth, Jupiter, and Saturn. This is due to the planet’s lopsided magnetic field. The magnetosphere tail behind Uranus opposite the Sun extends into space for millions of miles.

Voyager ' s observations revealed that Uranus's magnetic field is peculiar, both because it does not originate from its geometric centre, and because it is tilted at 59° from the axis of rotation. [ 135 ] [ 136 ] In fact, the magnetic dipole is shifted from Uranus's centre towards the south rotational pole by as much as one-third of the ...

2024年11月25日 · Earth, Jupiter, and Saturn all have dipolar magnetic fields, meaning they have a north and south pole — the type of configuration we’re obviously used to. But Uranus and Neptune don’t....

2017年7月12日 · These effects combine to not only give Uranus a more a more variable magnetosphere, but suggest the planet's magnetic field may be generated by a different mechanism than that of Earth, Jupiter and Saturn. For these visualizations, the magnetic field structure is represented by gold/copper lines.
