Mesopotamian bricks hold secrets of Earth’s magnetic history.

Mesopotamian bricks contain iron compounds that align with the Earth’s magnetic field during their formation. By studying the magnetic alignment preserved in these ancient bricks, scientists can deduce the intensity of Earth’s magnetic field at the time of their creation. This analysis provides valuable information about variations in the strength of the planet’s magnetic field throughout history, offering insights into past geomagnetic conditions and their potential impacts on Earth’s geological processes and ancient civilizations.
