Scientists at North Carolina State University (NCSU) have created a magnetic “metasheet” that can move objects and liquids around without needing robot arms or grippers. The device is essentially a ...

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 ...

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

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