Hidden mega-structures deep inside Earth may have been quietly steering our planet’s magnetic field—and rewriting what we ...

Every few years, the sun seems to change its mood. Dark spots appear and ...

Solve the falling wire problem to find terminal velocity in a magnetic field. See how motion through a magnetic field induces an emf and current, creating a magnetic force that opposes the fall ...

Most of the time, the shape of Earth’s magnetic field is quite similar to that which would be produced by a bar magnet ...

Deep inside Earth, two massive hot rock structures have been quietly shaping the planet’s magnetic field for millions of ...

All celestial bodies—planets, suns, even entire galaxies—produce magnetic fields, affecting such cosmic processes as the solar wind, high-energy particle transport, and galaxy formation. Small-scale ...

Scientists are mapping the Milky Way galaxy’s invisible magnetic field, revealing how it holds the galaxy together and ...

Inverse problems for magnetic Schrödinger operators are at the forefront of mathematical physics and analysis, as they address the challenge of determining unknown magnetic and electric potentials ...

This shifts our entire perspective on what makes a planet “Earth-like.” Nature is far more creative than our own solar system suggests. The universe might be teeming with “magma-shielded” worlds that ...
