Bogong moths use stars and Earth’s magnetic field to navigate epic migrations - revealing the first known stellar compass in ...

Australia’s iconic bogong moths are the first creatures other than humans and some birds known to navigate by the night sky.

They then applied a rotating magnetic field, which caused the particles to form crystals in different shapes: Sometimes they formed dense circular clusters, ...

Microscopic magnetic particles driven by rotating fields exhibit spontaneous edge currents, with particles at the boundaries moving faster than those in the center.

The findings, published Wednesday, December 18 in the Cell Press journal Device, suggest that these microrobot swarms—operating under a rotating magnetic field—could be used to take on ...

The patent US12074477B2 describes a rotating electrical machine system that integrates a rotor with a field element featuring a magnet portion composed of multiple alternating magnetic poles.

Systems that use magnetism to levitate objects, such as maglev trains, magnetic bearings, and flywheels, generally use a 'feedback mechanism' to stabilize the magnetic field.

The sun’s slowly rotating magnetic field induces an electric current in a huge surface that extends from our star’s equator far out into the solar system.
