WEST LAFAYETTE, Ind. - Researchers at Purdue and Duke universities have developed a technique that uses a magnetic field to selectively separate tiny magnetic particles, representing a highly ...
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 ...
No matter how its done, with whatever level of fakery, magnetic levitation just looks cool. We don’t know about you, but merely walking past the tackiest gadget shop, the displays of levitating and ...
In the supplemental material the experimental setup is shown (see top image), which is designed to make the individual iron-coated polymer particles rotate. The particles are called Janus particles ...
Smaller, streamlined electronics make lubricant-free, low-friction magnetic bearings feasible for more rotating machines. • Magnetic bearings support rotating shafts in five axes without solid or ...
