Abstract

Recent paleomagnetic data (Coe & Prevot, 1990, pp. 292–298; Humphreys, in press) strongly supports my hypothesis (Humphreys, 1986, pp. 113–126) that the earth's magnetic field reversed itself rapidly during the Genesis Flood. This paper shows specifically how convection upflows of the electrically conductive fluid in the Earth's core would produce such rapid reversals. The analysis shows that (a) the upflows had to have been faster than 3 m/s and larger than 5 km in diameter, and (b) each reversal would decrease the strength of the field slightly. All the evidence indicates that the Earth's magnetic field has continuously lost energy since its creation, implying that the field is less than 9,000 years old.
