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.
What's the scam? Bad guerrilla marketing? There isn't a call to action or advertisement or product to buy.
publicity stunt, maybe a lie but based on what we currently know, i wouldn't call it a scam
What’s with the period thing? Do people edit that into their comments after the fact or something?
