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 ...

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.

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 ...

Understand electric and magnetic forces through a clear velocity selector example! In this video, we break down how charged particles behave under electric and magnetic fields, explain the underlying ...

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 ...

Voyager 2, NASA's legendary interstellar probe, continues to deliver. Thirty-one years after the spacecraft cruised past Uranus, researchers have capitalized on the spacecraft's recordings to take a ...

Bioengineers have demonstrated that a gel-like material containing tiny magnetic particles could be used to manage chronic pain from disease or injury. Broadly, the study demonstrates the promising ...

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 ...
