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 ...

Physicists weren’t sure why Moon rocks brought back during the Apollo missions are more strongly magnetized than models predict ...

Scientists discover that the Earth's magnetic poles can take up to 70,000 years to reverse, much longer than previously ...

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 ...

Forbes contributors publish independent expert analyses and insights. David Bressan is a geologist who covers curiosities about Earth. Without its magnetic field, life on Earth would not be possible ...

Scientists studying lunar samples have finally resolved a decades-long debate about the Moon’s ancient magnetic field.

Recently the MagQuest competition on improving the measuring of the Earth’s magnetic field announced that the contestants in the final phase have now moved on to launching their satellites within the ...

(Nanowerk News) Physicists at RIKEN have demonstrated how ultrafast, low-power-consumption memory devices could be realized by replacing conventional magnetic materials with novel ones ...
