In what ways do the magnetic fields of both Uranus and Neptune defy the conventional Dynamo Theory for planetary magnetic fields?
What will be an ideal response?
The planet's rotation, as the word dynamo implies, is paramount in generating the magnetic field, so the field should align itself with the rotational axis; in other words, the N needle on a compass should really point north. For Saturn, it is fine, but at Earth and Jupiter, the field is off by about 10 degrees. However, for Uranus this magnetic tilt is 59 degrees, and even for Neptune it is 47 degrees off. Also, the core of the planet should contain the electrically conductive fluid that generates the field, but for both green giants, the fields do not pass anywhere close to this core.
