For nearly a century, geoscientists who believe the earth is billions of years old have been striving to develop a successful "dynamo" theory to explain how the earth's magnetic field might maintain itself over that long time. After reviewing analytic theories, computer simulations, and laboratory experiments, I have concluded that all those efforts have fallen short of proving the geomagnetic field could be maintained by a dynamo. To contrast with this apparent failure, I touch upon the remarkable success of creationist theories in explaining magnetic fields in our Solar system, especially the planet Mercury. This contrast supports the young Biblical age of the world, about 6,000 years.
