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 ...

One of the primary ways that gyroscopic motion can be applied is in the monitoring and/or maintaining of the orientation of an object. A broad array of engineering applications are based on gyroscopic ...

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

Liang and Lim spent three "grueling" years developing a recipe to make the panels by lithography, Cohen said. While the magnetic dipoles are all the same magnitude, the direction of the dipoles can be ...
