Robot collective Magnetic microrobot swarms act as motors to move millimetre-sized passive objects without physical contact. (Courtesy: MPI-IS) Strong viscous interactions exist in microscale systems, ...

Researchers have developed a novel device that couples magnetic fields and kirigami design principles to remotely control the movement of a flexible dimpled surface, allowing it to manipulate objects ...

Researchers found friction can occur without contact, driven by magnetic dynamics, and does not always increase with load. The effect could enable controllable, wear-free technologies.

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 ...

The relationship between friction and load, quantified three centuries ago, has an exception when the interaction causes ...

Researchers have uncovered friction without contact—driven entirely by magnetic interactions. As two magnetic layers slide, ...
