Charles Darwin strongly promoted the idea that life was generated spontaneously from non-life.
However, Louis Pasteur, a French microbiologist and believer in biblical creation, made a startling discovery that turned this notion completely upside down.
When the dipole moment is strong, carbon-14 production is suppressed below normal; when it is weak, carbon-14 production is boosted above normal.
What the magnetic field does is to partially shield the earth from cosmic rays which produce carbon-14 high in the atmosphere.
Rather, it's a way to determine the age of organic remains such as bone, teeth, and seeds by finding out how much carbon-14 is left in the remains. At the very least you'll find out what it's like to date a 9,000-year-old skeleton such as Kennewick Man's.
