A magnetometer is a device that measures magnetism: the direction, strength, or relative change of a magnetic field at a ...

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 ...

Nearly 200 years ago, a scientist named Michael Faraday tried experimenting to see whether Earth's magnetic field could help humans generate electricity for practical purposes. He concluded that ...
