You have a wire that is carring an AC current through a magnetic field caused by two magnets. The current flowing in the wire is in the X direction and the magnetic field is in the Y direction. In ...

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.

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 ...
