The inhibition of movement via eddy currents works best while the needle is moving fast, so you can still end up with smaller oscillations for a while - the apparent jump-cut to a stationary needle could be hiding that. It's far easier to just use a compass with a needle brake - manually dampen the oscillation using the brake (and let go to ensure you aren't holding an incorrect reading) and you get a reading quickly.

Not sure holding a break and making sure to release it to have a correct reading is any easier than something like this (if this is real).

  No, they're right and besides the video is fake so there is a fair chance this is a scam.

      Would you mind checking again? I haven't found any new comments that note the spliced video and old ones I have replied to as well got removed. If someone knows a way to unremove comments, this is the link to one: https://www.youtube.com/watch?v=eiDhbZ8-BZI&lc=UgzCu8FPM4CtRrb07NV4AaABAg.ARSkt5Yqv9SARgQy3rQV3N https://www.youtube.com/watch?v=eiDhbZ8-BZI&lc=UgzCu8FPM4CtR...

        The comments on this site (HN) may be what most people are talking about. Youtube comments are too easily censored, so they probably will never manage to stick around.

    What's the scam? Bad guerrilla marketing? There isn't a call to action or advertisement or product to buy.

    What’s with the period thing? Do people edit that into their comments after the fact or something?
    - hrimfaxi 8mo ago
      I think so as you can't delete a comment once it has children.

        Ah so saving face

    publicity stunt, maybe a lie but based on what we currently know, i wouldn't call it a scam
