In the original video he flipped it 360 degrees off the center of the magnet yet it kept the angle it was pointed at. Wouldn't a ferromagnet want to stay orientated with the field of the magnet and flip the other direction when rotated?
- AnotherGoodName 3y agoThat thread above has him flip the magnet and the same thing happens. Note the sample isn't magnetized itself, it's just ferromagnetic so conducts the field so the tip of the sample is the same and the top of the magnet (and this repels). That happens regardless of flipping the magnet.
- postalrat 3y agoNot flipping the magnet, rotating the sample. In https://nitter.net/VanGennepD/status/1688052003216261120 https://nitter.net/VanGennepD/status/1688052003216261120 (the video with the rubiks cube) at around 20 seconds they rotate the sample around 360 degrees and it stays at the same angle. Normally I'd expect it would stay at the same angle of the magnetic field.
- AnotherGoodName 3y agoThe above twitter thread it looks like he does that too with the ferromagnetic material. He has a long chain of posts although the first post after the original video has him rotate the sample 180 degrees on top of the magnet (still points up) and then again back to the original position. He does have it flop on top of the magnet at some point and has to poke it back upwards but that happens in the original video too so meh. The way the object moves is just too similar imho. It looks like plain old ferromagnetic material of that shape does this.
