Latest Levitation Stories
University of Tokyo researchers have developed a new technique for levitating objects using sound, allowing the floating objects to be steered in three different directions.
UBC researchers have discovered a universal electronic state that controls the behavior of high-temperature superconducting copper-oxide ceramics.
Weizmann Institute scientists have taken a quantum leap toward understanding the phenomenon known as superconductivity: They have created the world’s smallest SQUID – a device used to measure magnetic fields – which has broken the world record for sensitivity and resolution.
Classical and high-temperature superconductors differ hugely in the value of the critical temperatures at which they lose all electrical resistance.
Advances in technology for computation and information storage always require to make the systems smaller and faster.
Understanding superconductivity – whereby certain materials can conduct electricity without any loss of energy – has proved to be one of the most persistent problems in modern physics.

A research team that includes a physics professor at Indiana University-Purdue University Indianapolis (IUPUI) has recorded a drastically reduced measurement of the Casimir effect, a fundamental quantum phenomenon experienced between two neutral bodies that exist in a vacuum.
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...
