The Earth's magnetic field has been getting weaker over the past few centuries. This weakening can be seen in data gathered ...

A giant dent in Earth's magnetic field is continuing to expand, according to the latest data from a trio of satellites monitoring our world.

Satellite data reveal that a weak region in Earth's magnetic field has grown by an area roughly half the size of continental Europe in the last 10 years.

Geophysicists from ETH Zurich and SUSTech, China, have demonstrated the dynamo effect of the Earth’s core in a model in which viscosity has no influence, as is the correct physical regime for the ...

For more than half a billion years, a giant magnetic anomaly buried in Earth’s ancient rocks has puzzled scientists. The ...

Moroccan rocks reveal that Earth’s magnetic field once changed fast but followed a hidden order, helping scientists map ...

A new analysis of computer simulations of Earth’s magnetic field suggests that its behavior was different early in Earth’s history, resulting in greater stability and fewer reversals of the magnetic ...

This expanding anomaly exposes satellites passing over the region to heightened cosmic radiation and charged solar particles, ...

A tree-ringed African lake has yielded a record of Earth's magnetic field spanning the past 150,000 years. A core of rock and sediment drilled from the bottom of Lake Chala, a picturesque crater lake ...

Learn about the growth of the South Atlantic Anomaly, a region where Earth's magnetic field has significantly weakened.

Magnetic field data collected by ESA's Swarm satellites and other sources has been coverted into these frightening sounds.

As with any such correlation, one has to entertain the notion that said correlation might be spurious or indirectly related before assuming a strong causal link. Here it is for example known already ...
