Earth’s magnetic field has long been framed as a planetary force field, a protective bubble that keeps the worst of the Sun’s ...

Scientists in the United States have created a small device that produces a tiny electrical signal from Earth’s natural rotation. Although the voltage is extremely small, the experiment shows that ...

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 ...

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 ...

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 ...

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 ...

Scientists discovered Earth’s magnetic field is weakening over the Atlantic Ocean, but what does that mean for life on the ...

New research shows that light’s magnetic field is far more influential than scientists once believed. The team found that this magnetic component significantly affects how light rotates as it passes ...

Once the required magnetic force is defined, scaling up production with a constant magnetic force separation device becomes a rather straightforward task. After validating the magnetic force at a ...

Deep in Chile’s Atacama Desert, scientists studied a green crystal called atacamite—and discovered it can cool itself dramatically when placed in a magnetic field. Unlike a regular fridge, this effect ...
