An unusual reduction in the strength of Earth's magnetic field between 591 and 565 million years ago coincided with a significant increase in the oxygen levels in the atmosphere and oceans ...

The world's strongest magnet isn't just science fiction: it's real, ridiculously powerful, and used in some truly fascinating ...

Life on Earth may exist thanks to a brief faltering in our planet's protective magnetic field shell, scientists have found. A bizarre drop in the strength of the magnetic field has been found to ...

Ancient bricks inscribed with the names of Mesopotamian kings have yielded important insights into a mysterious anomaly in Earth's magnetic field 3,000 years ago, according to a new study.

The researchers found that rocks dating from 3.7 billion years ago captured a magnetic field strength of at least 15 microtesla comparable to the modern magnetic field (30 microtesla).

Strength of the magnetic field at Earth's surface. (ESA) The last such cataclysmic event occurred about 41,000 years ago, leaving a signature in the Laschamps lava flows in France.

Earth's magnetic field became weaker during this period, falling to at least 5% of its present strength. This made it possible for more cosmic rays to enter the Earth’s atmosphere, according to ...

Earth's magnetic field may have been similarly as strong 3.7 billion years ago as it is today, pushing the earliest date for this planetary protective bubble back 200 million years.

Earth is fortunate in having a magnetic field: it protects the planet and its life from harmful cosmic radiation. Other ...

The researchers found that rocks dating from 3.7 billion years ago captured a magnetic field strength of at least 15 microtesla comparable to the modern magnetic field (30 microtesla).

Using this method, [efeyenice983] found that the Earth’s magnetic field strength at their location was about 0.49 Gauss, which is well within 0.25 to 0.65 Gauss that is typically found on the ...

During a brief but dramatic chapter in Earth's history about 41,000 years ago, the planet’s magnetic field nearly collapsed. What followed was a cascade of environmental and biological changes ...
