My daughter has a plastic wand with a magnet. She grabbed my Garmin watch and tried to take it's pulse (PPG)...and it worked!? It reliably shows ~72bpm with some variation...but only on one side of the N/S magnetic polarity! 🤔 Can anyone explain? @DrSianAllen

Sounds like the beginning of a movie about an ancient artifact imbibed with magic.
