Only one of these should be Zel’dovich-amplified by the rotating cylinder (the co-rotating component) while the other is only ever absorbed, explains Cromb. “Ideally, we want to switch to a rotating ...

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.

The Barrett Chute refurbishment is part of OPG’s w ider effort to upgrade its hydro fleet, which provides about 20% of ...

The scientists injected Magnetospirillum bacteria into mice and with a rotating magnetic field, showed that they could bolster their ability to sneak through these temporary gaps in the vessel walls.

Rotating the magnetic field at specific speeds separates only particles of certain sizes, meaning pathogens attached to those particles would be separated from the sample by varying the rotation ...
