Recent satellite observations have unveiled a rapidly expanding weak spot in Earth’s magnetic field. This massive anomaly, ...

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

Per the ESA, this phenomenon can be best explained by strange behaviors far within the Earth at the boundary where the ...

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

The South Atlantic Anomaly, a strange dip in the Earth's magnetic field, has grown rapidly over the last eleven years, new ...

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

Geophysicists have modeled how Earth’s magnetic field could form even when its core was fully liquid. By removing the effects ...

To design an inductive component that contains a magnetic-core material, an engineer must accurately measure the material's characteristics. A magnetic core's dynamic hysteresis loop, or “B-H curve,” ...
