Learn how some of Earth’s magnetic field flips last longer than others, weakening our defenses against cosmic radiation.

In physics, we have a bunch of constants that are used in models to explain how the world works. These are fixed numbers that we plug into equations along with our variables. For example, the ...

The quest for the world's strongest magnet faced a surprisingly violent problem: they kept exploding. At least, that was the issue facing a group of scientists at the National High Magnetic Field ...

China has set a new benchmark in extreme magnet science after researchers built the ...

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 ...
