Researchers have shown that a pair of vertically arranged electromagnets can levitate and steer a magnetic robot inside a ...

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 ...

A detailed experimental analysis explains the forces by which a spinning magnet can cause another magnet to levitate in midair. An experiment with off-the-shelf components uses a magnet glued to 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.

Researchers at the Quantum Machines Unit at the Okinawa Institute of Science and Technology (OIST) are studying levitating materials—substances that can remain suspended in a stable position without ...

Superconductors are interesting things, though we don’t really rely on them for much in our day to day lives. They’d be supremely useful, if only they didn’t need to be so darned cold. While the ...
