1. In the video, they push the disc with a pen until it rolls over. They repeat it multiple times. It it were superconductive they could just position it in space without laying it on the magnets first.
2. The disc is not hovering.
3. The disc is damaged; one edge is thicker/heavier than the other. Thus causes the rolling. Notice that the heavier part always stays on the magnet. It it were superconductive they would be able use a uniform disc.
I call BS.
- blablabla123 3y agoWith a "regular" magnetic field you cannot even do this, it would roll over continuously. At least one point needs to be actually fixed. Also if I remember correctly it's mentioned that not the whole probe is superconductive but just part of it.
- jake_D 3y agoIt would not roll over continuously as it's affected by gravity as well. The heaviest part is at the bottom. And if it's not completely superconductive, what stops it from not being completely magnetic? For all we know, only the thin part could be magnetic, being repelled from the magnet below.
