Strange magnetic surges above the Moon have baffled scientists for years. A new model points to an unexpected plasma interaction as the culprit.

Primordial magnetic fields may help explain why measurements of the universe’s expansion do not agree. Scientists have long known that the universe is expanding, yet there is still no agreement on how ...

Use Faraday’s Law to solve the magnetic field detector problem by connecting changing magnetic flux to induced emf. Learn how coil area, orientation, turns, and time-varying fields affect the induced ...

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 ...

Earth’s magnetic field has long been framed as a planetary force field, a protective bubble that keeps the worst of the Sun’s radiation at bay. Increasingly, though, scientists are finding that this ...
