Earth’s Magnetic Field is Young
The earth’s magnetic field is a powerful witness for a world much younger than the billions of years required by evolutionary theories. Let’s start the story with the most prominent feature of the field today–its very rapid decay.The Field Is Decaying RapidlyThe average “intensity” of the earth’s magnetic field has decreased exponentially by about 7% since its first careful measurement in 1829.[1] The field’s intensity includes components of strength and direction and tells us the amount of force turning a compass needle northward. By estimating the field intensity everywhere (in, on, and above the earth), we can calculate the total electrical “energy” stored in the field. Such calculations show that the total energy in the field has decreased by about 14% since 1829. More . . .
