Magnetic field

Uranus has a magnetic field about 50 times stronger than Earth's. The axis of the field (an imaginary line joining its north and south poles) is tilted 59° from the planet's axis of rotation. The centre of the magnetic field does not coincide with the centre of the planet - it is offset by almost one-third of Uranus's radius, or nearly 7700 km. Because of the large angle between the magnetic field and its rotation axis, the magnetosphere of Uranus wobbles considerably as the planet rotates.

Voyager 2 passed through Uranus's magnetosphere as it flew by Uranus. The magnetic field traps high-energy, electrically charged particles, mostly r
