A giant dent in Earth's magnetic field is continuing to expand, according to the latest data from a trio of satellites monitoring our world. It's called the South Atlantic Anomaly, stretching across ...

Inside its boundaries, the magnetic field that radiates away from Earth's interior dips down to an altitude of about 120 miles (200 kilometers) above the planet's surface, which is much lower than the ...

Geophysicists have modeled how Earth’s magnetic field could form even when its core was fully liquid. By removing the effects of viscosity in their simulation, they revealed a self-sustaining dynamo ...

In recent years, NASA's Parker Solar Probe has given us a close-up look at the sun. Among the probe's revelations was the presence of numerous kinks, or "switchbacks," in magnetic field lines in the ...

Abstract: A kind of compact fiber optic vector magnetic field sensor is proposed. This sensor features a highly localized eccentric point-by-point fiber Bragg grating as its core component, with a ...

The magnetic field swirling around an enormous black hole, located about 55 million light-years from Earth, has unexpectedly switched directions. This dramatic reversal challenges theories of black ...

University of Warwick researchers have built a new diamond-based magnetic field sensor that could be used to better find tumors through tracing magnetic fluid injected into the body. Engineers at MIT ...
