Some asteroids can barely hold it together. Rather than solid lumps of rock, ‘rubble pile’ asteroids are loose collections of material, which can split apart as they rotate (SN: 3/16/20). To ...

In the world of magic, levitation looks like a simple spell. In movies and TV series, characters lift objects with a wave of ...

Magnetic levitation is a beautiful thing to watch. Seeing small objects wobble about while seemingly hovering in thin air never gets old. If you want something suitably distracting in this vein for ...

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 ...

The scientists chemically coated each graphite particle with a layer of electrically insulating silica. Polyethylene glycol (PEG) helps silica bind to the surface of the graphite. The coated graphite ...

Magnetic levitation systems harness the unique properties of high-temperature superconductors and permanent magnets to achieve frictionless, contactless motion. The core principle underpinning these ...
