Those magnets, the team says, are the most expensive part. "We have been able to show that shape-memory alloys are highly suitable for cooling cycles," says Oliver Gutfleisch, an author of the study.

Discover how powerful the strongest magnet on Earth really is, what it can do, and where it’s used in advanced scientific and industrial applications.

Since magnetic particles are sprinkled throughout the gallium, a permanent magnet can drag it around. In solid form, a magnet can move the material at a speed of about 1.5 meters per second.

What is special about the new material is that, unlike previous shape-memory materials, it consists of a polymer and droplets of a so-called magnetorheological fluid embedded in it. Areas of ...

Realta and WHAM, on the other hand, are working on a magnetic mirror design. In it, two strong magnets sitting some distance apart create a magnetic field that holds the plasma in a shape that ...

In fact, solar winds actually blow the magnetic envelope away from Earth in a tail shape. 🧲 You love our weird world. So do we. Let’s explore it together—join Pop Mech Pro.

The miniature electromagnet was created by MagLab engineer Seungyong Hahn. It generated a world-record 45.5 tesla magnetic field — more than 20 times the strength of a hospital MRI magnet.

A New Way to Shape Metal Nanoparticles—With a Magnetic Field Making the tiny nanoparticles used in everything from electronics to paint isn't easy. But a new experiment creates order out of chaos.
