Earth’s magnetic shield is shifting in dramatic ways. New data from ESA’s Swarm satellites show that the South Atlantic Anomaly — a vast weak spot in Earth’s magnetic field — has grown by nearly half ...

Earth’s magnetic field does not simply switch direction like a flipped light switch. It weakens, wanders, and reorganizes ...

Dive into the fascinating world of electromagnetism with Python Physics Lesson 30! In this lesson, we explore why a long wire generates a magnetic field and how current flow creates magnetic effects ...

Understand the magnetic field of two long wires with this detailed physics example! Learn how currents interact, how to calculate the resulting magnetic field, and visualize the principles behind ...

Every new generation of eyes sees a new version of our galaxy, the Milky Way. This Impressionistic swirl of color represents the churning magnetic fields in giant dust clouds near the center of the ...

Deep inside the Milky Way, an invisible force is quietly holding everything together — its magnetic field. Now, researchers have created one of the most detailed maps ever of this hidden structure, ...

Artistic visualization of a crystalline rod made of the semimetal ZrTe 5. There is a heat gradient from one end to the other. In its center, giant oscillations in its heat conduction are toggled by ...

A subtle twist between atomically thin magnetic layers can generate unexpectedly large and complex spin structures.

For a few brief nights each year, you get a rare chance to watch a monster blink. The Event Horizon Telescope collaboration ...
