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 ...

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

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 ...

Although magnetic forces are usually much weaker than gravity in shaping cosmic structures, the findings suggest that strong, ordered magnetic fields may have emerged earlier than expected. Over time, ...

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.

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 ...

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 ...
