We’re used to Hall effect devices as proximity sensors in mechanical systems, used to provide detection of something that has a magnet attached to it. However it’s easy to forget that the devices that ...

While strength is often visually represented in the form of cones, bars, or dots, it’s really calculated in the form of decibels per milliwatt, or dBm. A perfect signal is -30dBm, which you’ll ...

Invisibility has quietly shifted from fantasy to engineering problem, and the most convincing proof is not a shimmering cape but a magnetic cloaking device that makes fields themselves vanish from ...

Handgrip strength test: simple squeeze predicts muscle, heart health, ageing, and cardiovascular risk.

Argonne’s solenoid facility provides powerful magnetic fields for testing. A limiting factor in modern physics experiments is the precision at which scientists can measure important values, such as ...
