Who knew that magnetic fields could be so useful? Astronomers are able to use magnetic fields to map our environment within ...

Earth's Northern Lights typically dance near the poles, but 41,000 years ago, they lit up skies over North Africa and ...

Neutron star mergers are collisions between neutron stars, the collapsed cores of what were once massive supergiant stars.

During a brief but dramatic chapter in Earth's history about 41,000 years ago, the planet’s magnetic field nearly collapsed.

Scientists have long puzzled over why Mars, once protected by a global magnetic field like Earth, now shows only a magnetic imprint mostly concentrated in the planet’s southern hemisphere. A new study ...

Abstract: The optical fiber magnetic field sensors, which work near the dispersion turning point (DTP) or employ a long sensing fiber for phase difference accumulation, can achieve high sensitivity.

Based on the principle of sensing oil wear particles, the analytical model of coil magnetic field is established. The principle of wear particle detection and coil quality factor are analyzed, and ...
