@4:33 guy turns magnet disc around... **face palm* Dude, you know how physics works. ^^

Suchitra aks to turn the rail upside down. So I really do not know why you question the assistant when he did exactly what she wanted.

[@MrVankog]

For me it sounds more like she is explaining the general concept of turning it upside down. Meaning by that, to stick it on the roof instead of on the ground. Not necessarily to literally turn the track by 180°. I know it works without turning the plate, because in another video I actually saw this happen. ;-)

[@itsnotallrainbowsandunicor1505]

MrVankog You can do it to both sides as long as there are magnets on the other side, as in the video show casing a mobius strip. Otherwise, all the other videos that feature the magnets on just one side need the plate to be flipped over. The metal rim holding the magnets will not allow for magnetic levitation, only on the magnet side. You need to watch the videos again.

Paul Bevillard This seems strange to me, but you might be right. But shouldn't it be totally irrelevant on which side of the magnet you stick the super conductor to?

[@itsnotallrainbowsandunicor1505]

MrVankog One would think so. I have seen several videos where the support metal is extremely thin and thus poses no issue to levitation topside or bottom side. My guess is levitation is sensitive and having a think metal support for the magnets may interfere with the levitation somewhat. They could have the specimen float underneath without flipping the rail, but it may pose a problem such as keeping the specimen from falling. A question worth asking.
