Superconductors are among the most puzzling materials in physics. They conduct electricity with zero resistance, but only ...

Quantum metals are metals where quantum effects—behaviors that normally only matter at atomic scales—become powerful enough to control the metal's macroscopic electrical properties. Researchers in ...

A Superconducting Quantum Interference Device (SQUID) is an extremely sensitive magnetometer that measures very subtle magnetic fields. It exploits the quantum mechanical properties of ...

Traditional radio-based systems often suffer severe attenuation underground, as soil and rock absorb or scatter electromagnetic waves. By contrast, magnetic induction uses low-frequency magnetic ...

It is not known when humans first noticed the attraction or repulsion between pieces of magnetic material. The first important device depending on these forces was the magnetic compass, which is ...

PC-board layout sets the functional, electromagnetic interference (EMI), and thermal behavior of a power supply. Good layout from first prototyping on actually saves significant resources in EMI ...
