Magnetic flux leakage (MFL) testing is a widely established non‐destructive evaluation technique used to assess the integrity of ferromagnetic materials in applications such as pipeline inspection and ...

Inertial navigation systems based on quantum sensors, and other that use the Earth’s magnetic field, are under investigation.

A magnetometer is a device that measures magnetism: the direction, strength, or relative change of a magnetic field at a given location.

SBQuantum's quantum diamond magnetometer, as explained by CEO David Roy-Guay, is set to transform navigation and Earth ...

More than a decade of satellite monitoring has mapped Earth’s magnetic field as it subtly altered between 2014 and 2025 — and what scientists have learned is remarkable. The South Atlantic Anomaly, a ...

Forbes contributors publish independent expert analyses and insights. David Bressan is a geologist who covers curiosities about Earth. Nov 28, 2025, 07:59am EST Map of the strength of the Earth's ...

Recent research shows that magnetic fields can spontaneously emerge in a plasma if the plasma has a temperature anisotropy. This mechanism is known as the Weibel instability. This new research is the ...
