Magnetic Field Data Confirm Creation Model by Brian Thomas, M.S.
* Today, the earth's magnetic field strength is steadily
decreasing, but in the past it fluctuated. A recent study of an
ancient copper mine in southern Israel indicated just how
quickly those fluctuations could have occurred. What might have
caused this magnetic turmoil, and what does it imply? In their
study published in Earth and Planetary Science Letters,
researchers measured Iron Age copper slag at the ancient
smelting operation.1 The discarded metal had piled up over the
years into ten layers. Organic remains intermixed with the
layers were carbon dated and a tight chronology of the slag pile
was constructed.2 The copper slag contained tiny iron inclusions
that recorded the strength of the geomagnetic field at the time
it cooled and solidified. Wired Science reported, "They found
that the magnetic field abruptly spiked twice during the 180
years they studied, once around 2,990 years ago and once around
2,900 years ago."3 The study's author
