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

Long-term satellite measurements show that Earth’s magnetic field is changing faster and more unevenly than expected, driven ...

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 ...

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

Forbes contributors publish independent expert analyses and insights. An award-winning reporter writing about stargazing and the night sky. Using 11 years of magnetic field measurements from the ...

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 ...

Magnetic fields play an important—if sometimes underappreciated—part in planetary systems. Without a strong magnetic field, planets can end up as a barren wasteland like Mars, or they could indirectly ...
