There were so many spinning nuclei in the earth at creation that, if aligned, their fields would have added up to a large field of sufficient magnitude.
As thermal collisions disoriented the nuclear spins, the laws of electricity predict a startup of an electric current within the core of the earth to sustain the field.
The field strength should decrease by a constant percentage each year, and the data are consistent with such a decrease, implying that the field loses half its strength every 1400 years.
Such a rapid decay could not have continued for more than about 10,000 years; otherwise the initial strength of the field would have been impossibly high.
In 1986, Voyager 2 verified the Uranus prediction, and we should find out about Neptune in early 1990. After creation (and the Fall), the electric current in the earth's core would decay slowly, as would the field, for 1656 years, until the Genesis flood.
During this period, the field would have been more than ten times stronger than it is today, thus shielding the earth from cosmic ray particles more effectively, reducing the production of carbon 14 in the pre-flood atmosphere, and making the earth a healthier place. In 1986, I suggested that there was a powerful release of energy in the earth's core at the beginning of the Genesis flood, and that the resulting strong movements in the core field produced rapid reversals of the earth's magnetic field, about one per week, during the year that the flood was laying down the fossil layers at the earth's surface.
General physical laws allow rapid reversals, a likely physical mechanism exists to cause the reversals, and observations of the sun's magnetic field demonstrate reversal cycles in nature today.
Since the field has changed so violently in the past, old-earthers ask, how do we know the present decrease in the field is a decay, not a fluctuation or a reversal?
Furthermore, if a "dynamo" process did not start up the current in the core (as is becoming obvious by the problems with the theory), then how did the current originate?
Since the field probably started when the earth was formed, the present rapid decay of the field is strong evidence for a young earth.
