Earth’s magnetic field protects life from harmful cosmic radiation. But sometime between about 590 million and 565 million years ago, that security blanket seems to have been much thinner — with ...

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. Ancient ...

The weak spot in Earth’s magnetic field, a region over the South Atlantic where the field’s strength is significantly reduced compared to its surrounding area, has grown by an area nearly the size of ...

Forbes contributors publish independent expert analyses and insights. David Bressan is a geologist who covers curiosities about Earth. Without its magnetic field, life on Earth would not be possible ...

Driving an electric current through a molecule can create a magnetic field. Yet in practice, such fields are often too weak ...

Although the Earth’s magnetic field is reliable enough for navigation and is also essential for blocking harmful solar emissions and for improving radio communications, it’s not a uniform strength ...

At the right point of the orbit and stellar cycle, the star’s chromosphere brightens.

Permanent magnets play a crucial role in medicine due to its field strength, tunability of field and gradient distributions, as well as practical implementation. In a new study published in KeAi ...

Astronomers used winds on ultra-hot gas giant exoplanets to infer their magnetic fields' strength, finding them to be weaker than some expected. Credit: ESO / M. Kornmesser / L. Calçada illustration ...

Astronomers have made a series of landmark observations of one of the universe's most violent events. Using the U.S. National ...
