More than a decade of satellite monitoring has mapped Earth’s magnetic field as it subtly altered between 2014 and 2025 — and ...

The South Atlantic Anomaly, or SAA, has been known since at least the 1960s, but there were no detailed, continuous studies ...

Geophysicists have modeled how Earth’s magnetic field could form even when its core was fully liquid. By removing the effects ...

WEST LAFAYETTE, Ind. - Researchers at Purdue and Duke universities have developed a technique that uses a magnetic field to selectively separate tiny magnetic particles, representing a highly ...

If you made a motor out of a magnet, a wire coil, and some needles, you probably remember that motors and generators depend on a rotating magnetic field. Once you know how it works, the concept is ...

Researchers at the University of Tsukuba have developed a novel method for controlling the optical rotation of conductive ...

As Cassini continues its orbital finale around Saturn it has picked up on some interesting observations of Saturn’s magnetic field. Data gathered from Cassini’s magnetometer instrument have shown that ...

Researchers at OIST built a graphite disk that levitates and spins for hours in a vacuum, showing how perfect magnetic ...

With a clever design, researchers have solved eddy-current damping in macroscopic levitating systems, paving the way for a ...

The evolution of active regions generally has prevented the unambiguous detection of differential rotation by tracer or spectroscopic methods in disk-integrated solar and stellar observations. However ...
