What appears to be a curious trick – placing an AirPods case near a Chromebook and watching the screen turn off – is in fact a straightforward application of the Hall effect. Modern laptops employ Hall effect sensors near the hinge to detect whether the lid is open or closed. A constant current flows through the sensor, and when a nearby magnet is introduced, its magnetic field deflects the moving charge carriers. This deflection generates a measurable voltage, which the laptop interprets as the lid being closed. In this case, the magnet embedded in the AirPods case mimics the lid magnet, causing the Chromebook to enter sleep mode.

Oh lol i just push the corner of my laptop against my friends laptop charger port
Wait hall effect? Wooting 60HE? MERAMI HDDTHR ASCENSION TO HEAVEN
Gen-Z (OP) are a failed generation. GTFO
I had a magnet I don't know where I found it in class and we had chrokebooks. I signed into m8ne and then dragged the magnets across the touchpad and the computer restarted like three times over and then said it was missing it's memory or something.
That's science
🤓👆 erm actually now that computers have solid state drives, magnets don't effect the hard drive that much
This happened to myold phone😂
If you have another laptop like a MacBook or Microsoft with a magnetic charger, it does the same and freaks out everyone eith a chrome book, which mainly have hall sensors, especially the touchscreen ones
