Lenz’s Law is one of those physics tricks that look like magic if you don’t understand what’s happening. [Seth Robinson] was inspired by the way eddy currents cause a cylindrical neodymium magnet to ...

Here’s an impressive example of a completely home built magnetic levitation setup… with wireless power transmission to boot! [Samer] built this from scratch and it features two main sub-systems, a ...

Recently, I finished another simple version of my electromagnetic levitation demo device that levitates a small object under an electromagnet. What makes it different from my earlier model is the ...

When two magnets are placed facing each other with the same poles, they repel each other, and if you place one magnet under the other, it is possible to make one magnet float. However, simply ...

Glow is made from a synthetic material that gives it an ethereal glow. Inside are diode emitting low energy lights powered by lithium batteries. Two strength modes allow it to function as a task of ...

When we were all little kids, our earliest “science is cool” discoveries usually revolve around magnets. After all, everyone had a magnet or two lying around their house. For that kid in us all, the ...

A levitating magnetic microrobot autonomously sorts sub-millimeter particles by weight in 3D environments, enabling precise, contamination-free handling in biomedical and manufacturing applications.
