Archaeomagnetic dating problems
The resulting initial field strength is consistent with the present geomagnetic data and a 6000-year age for the field. Humphreys is an ICR Adjunct Professor of Physics and a physicist at Sandia National Laboratories, Albuquerque, New Mexico.Thus we have a plausible explanation for how the current in the core got started. The Laboratories have not supported this work, and they neither affirm nor deny its scientific validity.This rapid-reversal model not only explains the general features of the paleomagnetic data, but also some specific features which have puzzled evolutionists. The disturbances in the core fluid during the flood would disrupt the electric current, chopping much of it up into small swirls oriented in different directions. Then the earth's field during and after the flood would not have the simple "dipole" (two poles, north and south) shape it has today. Instead, it would have a more complex shape, with strong "higher-order" components: quadrupole (four poles), octopole (eight poles), etc. "An analysis of the earth's magnetic field from 1835 to 1965," ESSA Technical Report IER 46-IES I (July 1967) U.
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. Archaeomagnetic (magnetism of pottery, bricks, etc.) data indicate that the present steady decay started around 500 A. For several millennia before that, the overall strength of the field had fluctuated up and down significantly.Paleomagnetic (magnetism of geologic strata) data provide persuasive evidence that the field reversed its direction scores of times while the fossil layers were being laid down.Standard electromagnetic theory predicts that, after the flood, the higher-order components would die away faster than the dipole part. Because the higher-order components can have either polarity, the strength of the field would fluctuate up and down, as different components died away at different rates.
