The Earth’s Magnetic Field

An excerpt from my book (from chapter nine):

Scientists began measuring the earth’s magnetic field in 1829. Over a period of years, it has been discovered that this magnetic field is losing its intensity on an exponential basis. Further studies of ‘archaeomagnetism’ (the study of the magnetism in pottery, bricks and the like, from the past) reveal that around 1,000 years ago the earth’s magnetic field was approximately 40% stronger than it is today. Additionally, it has been decaying steadily since then. The challenge is to extrapolate the magnetic field back in time to some point when the intensity would have been too great for life to have been sustainable. If the magnetic ‘curve’ was extrapolated back 7,000 years, the magnetic field intensity would have been 32 times greater than it is today; it really could not have been much stronger than that since the earth would have melted from the heat of the core. However, it is also known that the magnetic field fluctuated quite a bit about the time of the Noachic flood. These fluctuations are combined, with the extrapolated curve on a graph, thanks to Dr. Russell Humphreys, to illustrate how this might have looked (see figure 1).

In the final analysis, considering the fluctuations, the steady decay and the time having passed, the loss of intensity in earth’s magnetic field agrees strongly with an earth that was created about 6,000 years ago. Furthermore, the near-term consequences of the diminishing magnetic field appear to validate a bleak outlook for earth’s future.
