Unveiling Mesopotamian Bricks: Clues to Earth's Ancient Magnetic Anomaly

Ancient Mesopotamian bricks inscribed with the names of kings have provided valuable insights into changes in Earth's magnetic field 3,000 years ago. By analyzing the magnetic signatures imprinted on iron oxide grains within the bricks, researchers were able to reconstruct the historical map of the Earth's magnetic field. This technique, known as archaeomagnetism, offers a new tool for dating artifacts that previously couldn't be dated accurately. The study also confirmed the existence of the "Levantine Iron Age geomagnetic Anomaly" and helped pinpoint the reigns of ancient kings. Additionally, the research suggests that rapid spikes in the Earth's magnetic field intensity are possible.
