Two vast, mysterious blobs of hot rock around Earth’s core may have been instrumental in producing Earth’s magnetic field and caused it to be slightly wonky for millions of years. Scientists have ...

Levon Pogosian receives funding from the Natural Sciences and Engineering Research Council of Canada. The work described in this article was enabled in part by support provided by the BC DRI Group and ...

Earth’s magnetic field is often treated as a steady planetary shield, but geological records reveal a far more dynamic and variable system. New research examining ancient ocean sediments suggests that ...

Deep inside Earth, two massive hot rock structures have been quietly shaping the planet’s magnetic field for millions of years. Using ancient magnetic records and advanced simulations, scientists ...

Explore the fascinating comparison between magnetic fields produced by a current loop and electric fields generated by a dipole. This short breaks down key similarities and differences using clear ...

It wasn't supposed to end that way, but the Baltimore Ravens' season ended up being determined by the foot of kicker Tyler Loop. After the Ravens and Pittsburgh Steelers swapped touchdowns on two ...

Abstract: This article addresses the conductor eccentricity error inherent in circular array Hall-effect current sensors through a novel magnetic field compensation ...

Our planet’s magnetosphere has seen dramatic shifts across its history—even total reversals—but this recent wrinkle doesn’t pose a threat to life Earth’s magnetic field surrounds the planet, with ...
