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 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.

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 ...

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

Ello!<BR><BR>So, a homopolar generator is really simple, at least in concept. Get a conductive disk spinning inside a magnetic field and the axel & edge acrue a voltage differential.<BR><BR>My ...

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 ...

Researchers at the University of Konstanz have uncovered a new mechanism of sliding friction: resistance to motion that ...
