Researchers found friction can occur without contact, driven by magnetic dynamics, and does not always increase with load. The effect could enable controllable, wear-free technologies.

When load increases steadily, so does friction, but in the realm of magnetization dynamics, things aren’t so simple.

Halbach magnet arrays represent an innovative approach in the design of permanent magnets for nuclear magnetic resonance (NMR) applications. By arranging magnets in a specific, asymmetrical ...

Researchers have uncovered friction without contact—driven entirely by magnetic interactions. As two magnetic layers slide, ...

While radiation treatments designed to kill cancer cells have come a long way, scientists and doctors are always exploring new ways to zap tumors more effectively. Recent tests at the U.S. Department ...

If you want a strong magnet, the obvious answer is to buy one. However, for a variety of reasons, you might want to combine several smaller magnets. There are a few ways to do this, but the Halbach ...

The magnetohydrodynamic (MHD) drive certainly sounds like something out of science fiction — using an array of magnets and electrodes, this high-tech propulsion technology promises to silently propel ...

The D’Onghia magnetic shielding crew hat, or CREW HaT, is a system that uses electromagnetic coils to deflect cosmic radiation from astronauts. The system consists of: A ring of electrical coils ...

Physicists show that magnetoelastic coupling, present in nearly all magnets, can generate skyrmion arrays without crystal ...
