Look at some fact: Mars lost its atmosphere, Mars has no mag field; the moon has no atmosphere, the moon has no mag field; Venus's atmosphere is not rotating, Venus has no mag field; the sun has an extensive rotating atmosphere, the sun has a huge mag field; Jupiter has a huge rotating atmosphere, Jupiter has a huge mag field; earth has some atmosphere, rotating, earth has some mag field. Mars has a rotating iron core but no mag field. The sun and Jupiter have no iron core, but guess what.

Sorry for jumping in a little late but

Titan has no magnetic field but it has a thicker atmosphere then Earth's and it appears to be rotating quite fast.

While Mercury has a magnetic field but for all intensive purposes has no atmosphere

So I don't see how an Atmosphere can be causing a moon/planet to have a magnetic field

I don't know how intense our purposes are, probably not very. You yourself have a magnetic field as was shown by the magnetic levitiation of the frog experiment. Do you have an iron core? What is the constituency of Titan's atmosphere? Is it dipoles?

Sorry, should have pinged you to #73 also.
