Voyager 2 found that the magnetic-field axis of Uranus is inclined nearly 60° to its rotation axis, and its center is displaced by a third of a radius from the planet’s center (Figure 10.18c). Considering the strange spin orientation of Uranus, this observation came as no great surprise. The total strength of the field averages 50 times Earth’s field, but the large displacement of Uranus’s field from the planet’s center causes the field at the cloud tops to vary between 0.1 and 1.1 gauss.
