Permanent magnets sit at the heart of the green economy, from wind turbines and electric vehicles to smartphones and industrial robots. For decades, the strongest versions have depended on rare-earth ...

In MIT’s Plasma Science and Fusion Center, the new magnets achieved a world-record magnetic field strength of 20 tesla for a large-scale magnet. In the predawn hours of Sept. 5, 2021, engineers ...

Georgetown University researchers have discovered a new class of strong magnets that do not rely on rare-earth or precious metals—a breakthrough that could significantly advance clean energy ...

A new initiative is emerging at the Princeton Plasma Physics Laboratory (PPPL), the U.S. Department of Energy national laboratory managed by Princeton University. Under the direction of principal ...

THE HUMBLE magnet may not seem to belong alongside steel, microchips and oil as a chess piece in the great diplomatic game. But on April 4th, as part of its retaliation against America’s tariffs, ...

If you want a strong magnet, the obvious answer is to buy one. However, for a variety of reasons, you might want to combine several smaller magnets. There are a few ways to do this, but the Halbach ...

If you grew up around some of the earlier models of televisions and computers, you may have received at least one sternly-worded warning to never place a magnet near them. These warnings still persist ...

Scientists are asking meteorite hunters to refrain from using magnets to test the authenticity of their finds because this can destroy the specimen's magnetic memory, erasing valuable information ...
