Two German physicists have reimagined how to create powerful and uniform magnetic fields using compact permanent magnets. By overcoming the limitations of the well-known Halbach array, which works ...
Europe is very close to making a huge move for its railway industry. A test by Italian firm IronLev has provided successful examples of how a magnetic levitation train, or maglev, might work on ...
(Nanowerk Spotlight) While investigations into magnetism predate 1820, it was Hans Christian Ørsted's discovery in that year that truly inaugurated the field of electromagnetism by demonstrably ...
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 ...

How a floating globe uses magnetic levitation to stay in the air
This video explores the science behind a floating globe that appears to defy gravity using magnetic levitation. It explains ...
Magnetic levitation is used to float everything from lightbulbs to trains, with varying levels of success, but usually it requires a power source. Now, scientists in Japan have developed a way to make ...
