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.

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 ...

When we hear about moving objects with electricity, most of us imagine a "pulling force." Positive and negative charges ...
