By studying what was once an iron smelting site in Cambodia, archaeologists and earth scientists unveiled a sharp change in Earth’s geomagnetic field direction and strength that occurred about 10 centuries ago. The new data, published this week in the journal Proceedings of the National Academy of Sciences, marks the first archaeomagnetism records from southeastern Asia. The researchers believe it will fill gaps in scientists’ understanding of Earth’s past magnetism, illuminating how the planet’s protective sheath may change in the future...
Tauxe worked with Mitch Hendrickson, an archaeologist at the University of Illinois at Chicago, who was excavating an iron-smelting site built by the Khmer Empire, which ruled Cambodia from the 9th century through the 14th centuries before collapsing. His team uncovered three iron furnaces at Tonle Bak, located in south-central Cambodia, which provided weapons and building material to fuel the Khmer Empire’s expansion beyond its capital of Angkor. Hendrickson’s team studied furnace fragments, slag waste left over from iron smelting, and tuyères, or air-delivery pipes.
When Tauxe and her team examined the iron waste, they found the Earth’s magnetic field moved suddenly westward and then eastward between 1200 and 1300. They also noticed a sharp decline in the field’s strength between 1100 and 1300.

thanks for the explanation.
I’m sure the ‘smart’ people are on it!
Bill Gates is working on a giant horseshoe magnet.
About 10 centuries ago.
In the Year of Cultural Awareness, we need to know:
Are they referring to metric centuries?
Or imperial centuries?
Or bisexual centuries?
And so on.
“Sharp shifts”...
How sharp is sharp?
I think they mean sudden leaps.
How sudden is sudden? How far is far?
In our lifetimes, the magnetic pole has shifted more than 1500 miles.
