The title is the headline of this article Scientists find 3,000-year-old glitch in the Earth's magnetic field thanks to some bricks (msn.com) . 

 

Here's a snippet -  " reconstructions suggest that a strange spike in the strength of the magnetic field – an event which has been dubbed the Levantine Iron Age geomagnetic Anomaly (LIAA) – occurred over modern-day Iraq between 1050 and 550 BCE. "

 

Does anyone have any ideas about what might have caused this ?
