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 ...

No matter how its done, with whatever level of fakery, magnetic levitation just looks cool. We don’t know about you, but merely walking past the tackiest gadget shop, the displays of levitating and ...

For more than a century, engineers have chased new ways to turn the planet’s natural motions into usable power, from tides to ...

Researchers have found that exposing a certain class of particles -- micron-sized beads endowed with a special magnetic sensitivity -- to a rapidly alternating, rotating magnetic field causes them to ...

Smaller, streamlined electronics make lubricant-free, low-friction magnetic bearings feasible for more rotating machines. • Magnetic bearings support rotating shafts in five axes without solid or ...

Scientists have developed swarms of tiny magnetic robots that work together like ants to achieve Herculean feats, including traversing and picking up objects many times their size. The findings ...
