Although the Earth’s magnetic field is reliable enough for navigation and is also essential for blocking harmful solar emissions and for improving radio communications, it’s not a uniform strength ...

A solar tsunami observed by NASA’s Solar Dynamics Observatory (SDO) and the Japanese Hinode spacecraft has been used to provide the first accurate estimates of the Sun’s magnetic field. Solar tsunamis ...

Space probes utilize magnetometers to measure magnetic fields in space, providing crucial data on celestial bodies' composition and interiors. Magnetometers function through various methods, including ...

A combination of standard and new observational techniques has been used to detect the magnetic field of a molecular cloud — a region of the interstellar medium that collapses during star formation.

Now more than ever, permanent magnets and electromagnets play a critical role in today’s advanced applications. From high-performance electric motors to magnetic nano-machines and high-reliability ...

July 22 (UPI) --Astronomers have for the first time directly measured the powerful magnetic fields surrounding hot Jupiters, gas-giant exoplanets orbiting close to their host stars. Unlike Jupiter, ...

A University of California, Berkeley, geophysicist has made the first-ever measurement of the strength of the magnetic field inside Earth’s core, 1,800 miles underground. The magnetic field strength ...

Using atoms only a few billionths of a degree above absolute zero, a team of researchers has detected magnetic signals undetectable by any other existing sensor technology. Using atoms only a few ...

Physicists have developed a minuscule instrument able to detect extremely faint magnetic fields. At the heart of the superconducting quantum interference device are two atomically thin layers of ...
