Latest Levitation Stories
Just in time for the 100th anniversary to commemorate the discovery of superconductivity by the Dutch physicist Heike Kamerlingh Onnes on April 8, 1911, scientists from the Helmholtz-Zentrum Dresden-Rossendorf and the TU Dresden published their research results in the journal Physical Review B.

On April 8, 2011, the scientific community will celebrate the centennial of the discovery of superconductivityâ€”the ability of certain materials to conduct electricity without resistance when cooled below a specific temperature.
Scientists have found the strongest evidence yet that a puzzling gap in the electronic structures of some high-temperature superconductors could indicate a new phase of matter.
Japanese researchers have been immersing iron-based compounds in hot alcoholic beverages such as red wine, sake and shochu to induce superconductivity.
A researcher at the National Institute of Standards and Technology (NIST) has invented a method of making high-temperature superconducting (HTS) cables that are thinner and more flexible than demonstration HTS cables now installed in the electric power grid while carrying the same or more current.
Illinois researchers have documented the first observations of some unusual physics when two prominent electric materials are connected: superconductors and graphene.
As part of an ongoing effort to uncover details of how high-temperature superconductors carry electrical current with no resistance, scientists at Johns Hopkins University and the U.S. Department of Energy's Brookhaven National Laboratory have measured fluctuations in superconductivity across a wide range of temperatures using terahertz spectroscopy.
Material could be evidence of a new phase of matter debated by physicists; properties could be harnessed for future superconductors, computer electronics.
A new material with a split personality -- part superconductor, part metal -- has been observed by a Princeton University-led research team.
Maglev is a vehicle propulsion system that uses magnetic levitation to move a vehicle with magnets instead of wheels. The vehicle hovers a short distance above the guide way by magnets and also uses the magnets for motion. The operation of this system is quite and maintains less friction for improved acceleration and deceleration. Weather does not affect the performance of the vehicle. Currently, some trains make use of the Maglev system, but vacuum tube trains could allow a Maglev system...
An electromagnet, a magnet whose magnetic field is produced by the flow of electric current, works until the electric current ceases. The magnetic field in a simple electromagnet is created by a wire passing through it with an electric current. The strength of the magnet depends on the amount of current. By making the wire into a coil the magnetic field is concentrated. A straight tube coil is a solenoid. A stronger magnetic field can be produced by putting a ferromagnetic material, such as...
