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 ...

Solve the falling wire problem to find terminal velocity in a magnetic field. See how motion through a magnetic field induces an emf and current, creating a magnetic force that opposes the fall ...

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 separation has become increasingly popular in biomedical science and industry. This technology uses magnetic properties of micro/nano-sized particles to separate macromolecules of interest, ...

The joint development team of Professor Shibata (the University of Tokyo), JEOL Ltd. and Monash University succeeded in directly observing an atomic magnetic field, the origin of magnets (magnetic ...

"As the magma cooled to form what is today the world's solid outer crust, magnetism was locked into minerals containing iron, such as magnetite." When you purchase through links on our site, we may ...

For the first time in the history of solar observation, NASA has made the Sun’s invisible magnetic behavior visible. Using footage recorded during a recent flyby, the Parker Solar Probe has shown the ...

Solar flares, intense bursts of radiation and light emitted from the Sun, are usually followed by a coronal mass ejection, which is a massive amount of solar material and the magnetic field energy ...

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 ...
