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.

For the first time, researchers measured the magnetic pull inside a single bacterium, turning a biological mystery into hard ...

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, ...

Learn how to calculate and understand the force on a wire loop entering a magnetic field in this detailed physics tutorial! We break down the concepts of magnetic flux, Lorentz force, and induced ...

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 ...

Dive into the changing forces of Earth’s magnetic field, understanding how shifts, excursions, and regional anomalies have influenced navigation, wildlife, and human technology throughout history.

Deep inside the Milky Way, an invisible force is quietly holding everything together — its magnetic field. Now, researchers have created one of the most detailed maps ever of this hidden structure, ...

It is not known when humans first noticed the attraction or repulsion between pieces of magnetic material. The first important device depending on these forces was the magnetic compass, which is ...

Add Yahoo as a preferred source to see more of our stories on Google. Over 11 years of satellite data reveal that Earth’s magnetic field is reshaping. (CREDIT: Shutterstock) More than a decade of ...

In MFM, a magnetic-coated AFM probe interacts with magnetic field gradients from the sample, causing detectable forces on the probe's cantilever. To focus on magnetic interactions, MFM is often ...
