All celestial bodies—planets, suns, even entire galaxies—produce magnetic fields, affecting such cosmic processes as the ...

The design of magnetic resonance imaging (MRI) gradient coils is a critical element in optimising image quality and system performance. These coils generate spatially varying magnetic fields, which ...

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 ...

An international group of researchers has found that chiral phonons can create orbital current without needing magnetic elements – in part because chiral phonons have their own magnetic moments.

The static magnetic field of an MR system is always on. No sound, sight, or smell alerts personnel to the presence or the extent of the invisible field surrounding the magnet in all directions. The ...

Magnetic tweezers are a versatile single-molecule manipulation technique that uses magnetic fields to apply forces and torques on magnetic particles attached to biological molecules, such as DNA, RNA, ...

For more than a century, engineers have chased new ways to turn the planet’s natural motions into usable power, from tides to geothermal heat. Now a small group of physicists says Earth’s own magnetic ...
