In the world of particle physics, you are never alone — quite literally. Every moment there is an invisible rainstorm of subatomic particles falling down on us from space. Unlike the kind of matter we ...

Traditional magnetic separators, however, present a challenge: they generate a magnetic force that is very high near the side of the vessel closest to the magnet and decreases rapidly with distance.

Magnetic levitation demonstrated using a Dremel tool spinning a magnet at 266 Hz. The rotor magnet is 7x7x7 mm3 and the floater magnet is 6x6x6 mm3. This video show the physics described in the work ...
