The discovery of the quantum Hall effect in 1980 marked a turning point in condensed matter physics. The measurement of the Hall resistance showed that electronic resistance could be defined precisely ...

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 ...

What is the Hall Effect? The Hall effect is a fundamental phenomenon in physics that occurs when an electric current flows through a conductor in the presence of a magnetic field perpendicular to the ...

Hall effect sensors are everywhere right now. Keyboards, game controllers, and DIY kits use them for more precise inputs. But with any newly popular device, it can be easy to immediately jump onto the ...

On an autumn day in 1879, Edwin Hall was at his bench in Johns Hopkins University's physics lab, a converted kitchen off Baltimore's North Howard Street called the Annex. The third-year graduate ...
