Claim

Earth's magnetic field is decaying at a rate indicating that the earth must be young.

Responses

1. The current mainstream model for the earth's magnetic field is a dynamo model which would cause occasional drops in the magnetic field's intensity and even total reversals. Paleomagnetic data confirms that historically the magnetic field has changed in a way similar to what one would expect from the dynamo model. Assuming a constant decay rate, as this claim does, is a naive, unthinking approach not covered by any working models.
2. The earth's magnetic field is driven by fluid motion in the core, and it has been recorded by ferro-magnetic minerals for 3 billion years. Since the work of Königsberger (1938) and Carpozen (Nature, 2004), there is some strong physical evidence against Earth having been created in 6 days, 6000 years ago.
3. YECs argue against geological uniformitarianism, which is supported by mass amounts of evidence. However, they make a uniformitarion assumption in the magnetic field argument, and their assumption is not even supported by the evidence.
