Magnets can move metal objects without even making contact—but how do they do that? In this video, you’ll learn how magnetic fields are formed, how poles attract and repel, and where we see this ...

Instead of physical contact, these 300-micrometer robots use fluidic torque — creating controlled whirlpools in the surrounding liquid to exert force on objects ...

Researchers have commanded swarms of magnetic microrobots to manipulate, rotate, and assemble objects without ...

Tiny magnetic microrobots spinning in liquid can generate fluidic torque strong enough to move gears and objects without any physical contact.

Linear motors are becoming increasingly practical for general motion. Many are used for long strokes of a few feet or more. One new design, however, where the magnets move relative to a stationary ...
