Measuring a magnetic field can be very easy with some pretty low tech, or it can be very high tech. It just depends on what kind of measurement you need and how much effort you want to expend. The ...

Paragraf presented a Hall sensor made of graphene for cryogenic applications, such as quantum computing, high-energy physics, low-temperature physics, fusion, and space. Conventional materials find it ...

November 3, 2013. Measuring electrical current in a conductor is critical to many systems. Classic measurement techniques use shunt resistors, current transformers, or magnetic field sensors.

Sensing current, especially in higher-voltage settings, is often a challenge. It’s generally more difficult than voltage sensing, as it is usually “invasive” and requires “breaking” into the ...
