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 ...

One of the common modes of scanning probe microscopy (SPM) is Magnetic force microscopy (MFM). As indicated by the name, SPM is used to map magnetic properties. On the nanoscale, MFM probes local ...

Traditional magnetic separators, however, present a challenge: they generate a magnetic force that is very high near the side of the vessel closest to the magnet and decreases rapidly with distance.

How fast can a galaxy build ordered magnetic fields spanning thousands of light-years? Existing theories say several billion years, but observations of galaxies in our universe imply shorter ...

If you took introductory physics, you learned about the “fundamental forces.” It goes something like this: All interactions are the result of one or more of five basic forces: strong nuclear, weak ...

Military leaders have been warning of the fragility of GPS for years and researchers have been working on a variety of solutions, from quantum clocks to inertial navigation. The Air Force is adding a ...

Magnetic force microscopy (MFM) is one of the modes of scanning probe microscopy (SPM). As the name implies, it is used to map magnetic characteristics. MFM investigates the local magnetic fields at ...
