What are solid body magnetic fields like and what CAN they be like?
The geomagnetic field is known to have reversed sometimes.
How long does a geomagnetic reversal last? And what is the magnetic
field like while a geomagnetic reversal is in progress?
There is no selenomagnetic field - but there is remanent
magnetization. Was there a selenomagnetic field once upon a time?
There is no areomagnetic field, either. But there is the banded
pattern of remanent magnetization. Did the areomagnetic field undergo
reversals?
There is no cytheromagnetic field. Is there any remanent magnetization
of Venus?
Does the hermeomagnetic field have any variability? Do hermeomagnetic
reversals occur?
What about the ganymedeomagnetic field?
