Have you ever wondered how induction cooking works? A rotating magnetic field — electrically or mechanically — induces eddy currents in aluminum and that generates heat. When [3D Sage] learned this, ...

Permanent magnets aren’t typically switchable. They’re always doing their magnet thing. However, if you align them with a bunch of other magnets in just the right way, you can create a permanent ...

Additive manufacturing can turn everyday magnetic material into alternatives for expansive rare-earth magnets. Engineers at the Amess Laboratory’s Critical Materials Institute used laser 3D metal ...

Physicists at the Ural Federal University (UrFU, Ekaterinburg, Russia) will print unique magnets, magnetic systems, soft magnetic elements with a 3D printer. Samples made with this printer can be ...

Researchers in California have created an incredibly small robot that needs no battery or wired power supply to zip through the air. Instead, it uses magnets to fly. A magnetic field produced by an ...

From wind turbines and electric motors to sensors and magnetic switching systems: permanent magnets are used in many different electrical applications. The production of these magnets usually involves ...
