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 ...

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

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 ...

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 ...

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

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 ...

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

New radio observations of the Milky Way are exposing hidden patterns in its magnetic field. People have scanned the night sky for ages, but some of the Milky Way’s most important features cannot be ...

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

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 ...
