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

Explore the fascinating world of magnets with a variety of fun and educational experiments using everyday objects. Watch as we test the magnetic properties of apples, stack iron coins using a ...

Fusion power may be a more realistic prospect than you think. As Motherboard reports, researchers at the Energy Department's Lawrence Livermore National Laboratory have discovered that a new magnetic ...

You’ve probably heard the term magnetic gradient before, but have you ever seen one? Now you can in [supermagnetman’s] video, below. The key is to use very fine (2 micron) iron filings and special ...

New research published in Physical Review Letters suggests that superconducting magnets used in dark matter detection experiments could function as highly precise gravitational wave detectors, thereby ...

A new initiative is emerging at the Princeton Plasma Physics Laboratory (PPPL), the U.S. Department of Energy national laboratory managed by Princeton University. Under the direction of principal ...

Historically, prior to 1820, electricity and magnetism were thought to be separate entities of nature. On April 21, 1820, Hans Christian Oersted, a Danish physi ...

In most conventional semiconductors, thermal conductivity decreases as temperature rises because heat-carrying lattice vibrations—called phonons—scatter more frequently.
