This paper closes a loophole in the case for a young earth based on the loss of energy from various parts of the earth’s magnetic field. Using ambiguous 1967 data, evolutionists had claimed that energy gains in minor ("non-dipole") parts compensate for the energy loss from the main ("dipole") part. However, nobody seems to have checked that claim with newer, more accurate data. Using data from the International Geomagnetic Reference Field (IGRF) I show that from 1970 to 2000, the dipole part of the field steadily lost 235 ± 5 billion megajoules of energy, while the non-dipole part gained only 129 ± 8 billion megajoules. Over that 30-year period, the net loss of energy from all observable parts of the field was 1.41 ± 0.16 %. At that rate, the field would lose half its energy every 1465 ± 166 years. Combined with my 1990 theory explaining reversals of polarity during the Genesis Flood and intensity fluctuations after that, these new data support the creationist model: the field has rapidly and continuously lost energy ever since God created it about 6,000 years ago.
