Rescuing Magnetic Field Speculations of an Old Earth
Earth's magnetic field cannot last for billions of years. Biblical creationists frequently point out this fact, and secular scientists also admit this fact. The evidence shows a young Earth, but that does not fit into the paradigm necessary for evolution to occur, so rescuing devices have been put forward. None have been plausible.

The simple story for the public: a dynamo creates the Earth’s magnetic field. The real story: complex scenario needed to start it and keep it running. Science is often like the two-headed Roman god Janus: one face for the insiders, a different face for the outsiders. Geophysicists have locked themselves into an explanation for the Earth’s magnetic field—the only one, in fact, that offers any hope for keeping it going for billi
