Understand the magnetic field of two long wires with this detailed physics example! Learn how currents interact, how to calculate the resulting magnetic field, and visualize the principles behind ...

What is Magnetic Force Microscopy (MFM)? Magnetic Force Microscopy (MFM) is a scanning probe microscopy technique that allows the imaging and characterization of magnetic properties of materials at ...

Learn how some of Earth’s magnetic field flips last longer than others, weakening our defenses against cosmic radiation.

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, ...
