Decay of the Earth's Magnetic Field Proves the Earth is Young

The Earth's magnetic field is decaying at a rate that would suggest that it will be zero in a few thousand years. If one extrapolates back, it would be too strong for an "old Earth". In fact, the earth's magnetic field has decayed and reversed many times throughout its history. One can find microfossils of certain kinds of bacteria that incorporate iron and see that magnetic "north" has been pointed to the South Pole in previous ages. Recent studies have shown that the Sun's magnetic field changes on an 11 year cycle that appears to be related to the fluid dynamics of its molten core. Likewise, the molten core of the earth rotates at a different rate than the crust of the planet, which accounts for tectonic activity.

Recently, a team of Swiss and American paleoclimatologists and particle physicists determined from the GRIP Greenland ice core that the intensity of Earth's magnetic field reached maxima at 2,000, 8,500, 22,000, 30,000, and 48,000 years ago.1 Over the past 35,000 years the Earth's magnetic field intensity has stayed within the range of one-half to twice its present value, refuting the claim that Earth must be younger than 20,000 years or that Earth's magnetic field intensity experienced dramatic oscillations during the flood of Noah.
