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, ...

Chain of magnets transports proton beams over range of energies in test of future cancer treatment
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 ...
