Physicists discover flaws in superconductor theory

University of Houston physicists report finding major theoretical flaws in the generally accepted understanding of how a superconductor traps and holds a magnetic field. More than 50 years ago, C.P. Bean, a scientist at General ...

Nanomagnets levitate thanks to quantum physics

Quantum physicists in Oriol Romero-Isart's research group in Innsbruck show in two current publications that, despite Earnshaw's theorem, nanomagnets can be stably levitated in an external static magnetic field owing to quantum ...

Trio create artificial magnetic wormhole

(Phys.org)—A trio of physicists with the Autonomous University of Barcelona has built what they claim is the first artificial magnetic wormhole. In their paper published in the journal Scientific Reports, Jordi Prat-Camps, ...

Keep cool: Researchers develop magnetic cooling cycle

As a result of climate change, population growth, and rising expectations regarding quality of life, energy requirements for cooling processes are growing much faster worldwide than for heating. Another problem that besets ...

Czech scientists develop magnetic carbon

A dream of many generations of researchers has been fulfilled by a discovery made by scientists at the Regional Centre of Advanced Technologies and Materials (RCPTM) at the Palacky University in Olomouc. By using graphene, ...

Magnetic cooling enables efficient, 'green' refrigeration

Magnetic cooling is a promising new refrigeration technology boasting several advantages – ranging from lower energy consumption to eliminating the use of hazardous fluids – that combine to make it a much more environmentally ...

Cloaking magnetic fields: The first 'antimagnet' device developed

Spanish researchers have designed what they believe to be a new type of magnetic cloak, which shields objects from external magnetic fields, while at the same time preventing any magnetic internal fields from leaking outside, ...
