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 bead separation is a fast, effective, and clean process that scientists use as an alternative to filtration and centrifugation techniques for separation. Magnetic beads and particles can be ...

Magnetism is a natural force, one that works at a distance. Magnets get their force from magnetic fields created by the atoms within the metal. Magnets are useful for things like turbines we use to ...

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 ...

Our planet’s magnetosphere has seen dramatic shifts across its history—even total reversals—but this recent wrinkle doesn’t ...

Light has always been described as an elegant partnership of electric and magnetic fields, yet for nearly two centuries ...

New research reveals how cryptochromes, magnetite, and electromagnetic induction help animals detect magnetic cues and find ...

In 1845, Michael Faraday discovered what’s known today as the Faraday Effect—which describes how light and electromagnetism ...

Researchers at the University of Hawaiʻi Institute for Astronomy (IfA) are helping reshape how scientists study the sun. The ...

Forbes contributors publish independent expert analyses and insights. An award-winning reporter writing about stargazing and the night sky. Using 11 years of magnetic field measurements from the ...
