Magnetism is a natural force, one that works at a distance. Magnets get their force from magnetic fields created by the atoms within the metal. Magnets are useful for things like turbines we use to ...

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 ...

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 ...

Researchers have uncovered friction without contact—driven entirely by magnetic interactions. As two magnetic layers slide, their internal forces compete, causing constant rearrangements that ...

Researchers have found that magnetic fields buried deep inside stars can survive their entire lifetimes and later reappear on ...

The little ornaments holding pictures to your refrigerator and the giant cranes picking up cars in a junkyard are all using magnets. Magnets attract objects made of certain metals. They can also push ...

Magnetism is usually taught as a story of straight lines, with field arrows marching neatly from north to south. In a lab at Florida State University, that picture has just been shattered by a new ...

Friction usually announces itself through contact. A chair scraping across a floor, a tire gripping asphalt, a hand sliding ...

From cardiovascular disease to cancer to gastrointestinal tract conditions, the incredible strength of neodymium iron boron (NdFeB) rare earth magnets is opening up exciting new opportunities for ...

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.

An F-16 Fighting Falcon from the 412th Test Wing’s 416th Flight Test Squadron performs a fly-by of the air control tower at Edwards Air Force Base, California, The fact that GPS is vulnerable to ...
