More than a decade of satellite monitoring has mapped Earth’s magnetic field as it subtly altered between 2014 and 2025 — and ...

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

The South Atlantic Anomaly, a huge weak spot in the geomagnetic field off South America, has expanded and sprouted a lobe in ...

A weak zone in Earth’s magnetic field, known as the South Atlantic Anomaly, has expanded at an alarming rate over the past ...

The weak spot, known as the South Atlantic Anomaly, was identified in the 19th century and expanded in recent years.

In a remarkable leap for quantum physics, researchers in Japan have uncovered how weak magnetic fields can reverse tiny ...

The Danish physicist Hans Christian Oersted was discussing in the year 1820 about the possibility of electricity and magnetism being associated to one another, and in the process presenting it finally ...

A magnet produces a vector field, the magnetic field, at all points in the space around it. It can be defined by measuring the force the field exerts on a moving charged particle, such as an electron.
