Researchers have unveiled a new magnetic cloaking device that can render sensitive objects invisible to detection.

For nearly 20 years, physicists and engineers have chased the idea of invisibility. Early efforts focused on hiding objects from light using so-called metamaterials with extreme and often unrealistic ...

As one of four fundamental forces in nature, magnetism is virtually everywhere in the world. Many technologies—hard drives, ...

Earth’s magnetic field has long been framed as a planetary force field, a protective bubble that keeps the worst of the Sun’s radiation at bay. Increasingly, though, scientists are finding that this ...

The Sun’s magnetic field is invisible to our eyes, but it quietly shapes everything from the shimmering auroras over the ...

A magnetic cloak works by diverting external magnetic fields so that, to an external observer, the object appears to be absent or invisible. Although this idea ...

An artist's concept of a massive solar burst, with Earth for scale. Illustration: NASA/GSFC/SDO Our Sun is a dynamic star, constantly bombarding our planet with charged particles that cause aurorae ...

Permanent magnets play a crucial role in medicine due to its field strength, tunability of field and gradient distributions, as well as practical implementation. In a new study published in KeAi ...

In other tests, the team carefully controls the magnetic fields in different areas to guide the robots through obstacle courses by crawling along the ground, jumping over moats, climbing walls, and ...
