If I were the authors of a theory some few years ago that the Earth was collided by the Moon which sent the Earth's axis on a 23 degree tilt, I would be more worried that it was all false. I say that because many of the planets seem to have large axial tilts, and we would be ludicrous in thinking that all of them were due to moon collisions.
I keep chiding myself to make a large table of facts and data, but so far only piecemeal tables.
axial tilt magnetic poles Earth 23 d. aligned approx same 1 gauss
Uranus 97 degrees 59 d. axis of rotation 1.1 gauss
Neptune 28 d 47 d. axis of rotation 0.2 gauss
I am going to abandon this search for a astronomical evidence of dB/dK although Mercury is a prime candidate since it is so near the Sun. But I abandon it because if we look at the Displacement Current in Ampere/Maxwell Law, we can expect a similar type of current in the Faraday law of its magnetic current density. So I need to focus on the Displacement Current to uncover what the magnetic current density should be and what dB/dK should be.
Google's archives are top-heavy in hate-spew from search-engine- bombing. Only Drexel's Math Forum has done a excellent, simple and fair archiving of AP posts for the past 15 years as seen here:
