Answer:
keeping their moons in orbit
Explanation:
Uranus is known to have 27 moons, and Neptune has 14 moons. The magnetic field of Uranus and Neptune are very irregular and have equators that do not orbit the planet. Unlike Earth, Jupiter and Saturn with fields oriented just within approximately ten degrees (10 degrees) of the spin axis, the magnetic field of Uranus and Neptune are there to keep their multiple moons in orbit.
