Earth’s magnetic field exhibits signs of being young and part of a grand design.

Saturn has its beautiful rings. Diamonds are often photographed adorning the fingers or the necks of beautiful women. Both Saturn and diamonds are testimonies to a young earth (which I wrote about here and here). The earth’s magnetic field is also a testament to a young earth – but it’s more than that; it’s a powerful testimony that God created it. But being invisible to the naked eye, earth’s magnetic field is at a distinct disadvantage in this visual age – requiring visual aids like the depiction of the field above. But make no mistake, the magnetic field around the earth is one of the most powerful testaments to a carefully and lovingly designed young earth that you’re likely to find. And what it lacks in glamour, it makes up for in the power of its evidentiary support of Genesis 1.1: In the beginning God created the heavens and the earth. Here’s why:
Evidences Gleaned from Earth’s Magnetic Field
1. Young earth
Old earth proponents will tell you that the earth is about 4 1/2 billion old. That means the magnetic field should also be about 4 1/2 billion years old. If that were true you would expect to have a magnetic field that’s very stable, not changing much over time – since we’re talking about a lot of time: not merely hundreds of years, or thousands or even millions of years, but billions with a “b”. The problem with that supposition is that it doesn’t match the observed measurements. It has been known for some time that the earth’s magnetic field is decaying. As geologist and creationist John D. Morris put it:
“The strength of the magnetic field has been reliably and continually measured since 1835. From these measurements, we can see that the field’s strength has declined by about seven percent since then, giving a half-life of about 1,400 years.”1
Obviously that’s a problem. A field decaying that quickly will last only a few thousand years not a few billion. And it’s gotten worse for old age earth believers: scientists have recently discovered that the field has begun to decay even faster:
“Previously, researchers estimated the field was weakening about 5 percent per century, but the new data revealed the field is actually weakening at 5 percent per decade, or 10 times faster than thought.”2
This does not bode well for the old earth explanation of a magnetic field that is billions of years old. Their explanation up to this point has been the field is created and maintained by a “dynamo”, a natural generator. Magnetic fields are created by the movement of electrons – a current flow. Scientist posit that the rotation of the earth and convection (movement due to heat) is sufficient to produce a current from the molten iron/nickel of the earth’s outer core, which they believe would create a self-sustaining field generating dynamo. The problem with the theory is that “Scientists have not produced a workable analytic model, despite 40-50 years of research, and there are many problems.”3
Creation Theory is Better Science
Contrary to claims that Creation Science is not really science because it makes no predictions and has no objective data that can be tested, creationist scientist Continue Reading
