On step 3,000 years back when you look at the old Mesopotamia, brickmakers imprinted the brand new labels of their leaders towards clay bricks. Today, an analysis of one’s material grains when it comes to those bricks keeps confirmed a mysterious anomaly in World’s magnetized industry.

A brick relationship into reign off Nebuchadnezzar II (circa 604 in order to 562 B.C.), with regards to the inscription. That it stone, which was looted which can be today housed regarding the Slemani Museum into the Iraq, although some assisted experts prove a historical magnetic industry anomaly.

Old bricks off Mesopotamia possess assisted prove a mystical anomaly for the Earth’s magnetic career that happened step 3,000 in years past, a new study discovers.

Brickmakers baked the bricks, which were imprinted with the names of Mesopotamian kings, between the third and first millennia B.C. Iron oxide grains within the clay recorded changes in Earth’s magnetic field when the bricks were heated, enabling scientists to reconstruct changes in the magnetic field over time, the team reported in a study published in the journal PNAS on Monday (Dec. 18).
