Abstract:

"God could have started magnetic fields in the solar system in a
very simple way: by creating the original atoms of the planets
with many of their nuclear spins pointing in the same direction.
The small magnetic fields of so many atomic nuclei add up to
fields large enough to account for the magnetism of the planets.
Within seconds after creation, ordinary physical events would
convert the alignment of nuclei into a large electric current
circulating within each planet, maintaining the magnetic field. The
currents and fields would decay steadily over thousands of years,
as Barnes has pointed out.

The present magnetic field strengths of the Earth, Sun, Moon, and
planets agree very well with the values produced by this theory and
a 6000-year age for the solar system.

This theory is consistent with all the known data and explains many
facts which have puzzled evolutionists."
