What in the actual crazy is going on ?
This is the 2nd time in a week where odd magnet results have appeared. I either have very duff meters or....nah, there has to be a reason. For a start, the probes are not bolted or clamped to the magnets, simply 1 is under the stack, the other is being pulled toward by the semi-flexible wire.
These magnet pieces are just snapped up HDD neos and a few very thin disc types as a small stack, half a dozen separate neo pieces in effect, with regular copier/printer type paper between.
Meter is a Uni-T 136B
It wasn't immediate, it started off at around 15mV and then climbed over a couple of minutes, until slowing down and ending up hovering at the 128mV level.
Hand oils on the magnets or magnet to probe junctions ?
Well, it only takes a minute to verify from other folks.
ETA: a quick 1min vid showing an odd effect.
If I sit the stack on just the Negative probe, the voltage climbs on the meter. Remove the stack, the voltage drops away. It should be a meter fault, with it not dropping to zero immediately, but, how come just placing on the 1 probe changes the values ?
Putting the stack on the Positive probe brings the reading down far quicker than no stack being present too !
A field effect ? yet with no oscillation ? https://www.youtube.com/watch?v=yM8KpP2ahPo
