Forbes contributors publish independent expert analyses and insights. David Bressan is a geologist who covers curiosities about Earth.

Two German physicists have unveiled a compact magnet layout that outperforms the famed Halbach array, delivering stronger, ...

"If the effect is real and scaling behaves the way our equations say, then the possibility becomes real," Chyba told Newsweek.

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

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 ...

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.
