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

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 ...

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

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 ...

Scientists have detected mysterious waves deep inside the Sun, uncovering hidden magnetic forces that drive solar activity.

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 ...

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 ...

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 ...
