At 1:55, we see a drop from the first side of the magnet. As we see it fall, we can tell that it is the rightmost corner that was standing. Take a look at the top edge - the two sequential dips. The bottom edge is a smooth-ish long curve that protrudes out to a bulb on the leftmost corner. Now let's go to 3:03 and do the same. Once again it is the rightmost corner that was standing, the same as before, even thought the magnet has been flipped, and the right edge has those two sequential dips, and the left edge has the smooth-ish long curve. However, let's go back to 2:05, and the original magnet position. We see it stand and fall, but we can tell that it was the leftmost corner this time, the one that has the long curve that ends in a protruding bulb - we had different corners in the standing position with the same orientation on the magnet, and the same corner set in the same standing position with the flipped orientation on the magnet. I don't fully understand why the same magnet orientation could result in different corners being stood up (though I would guess it is related to the object likely being diamagnetic), but the same corner standing up even when the magnet is flipped rules out a regular ferromagnetism, from my limited understanding.
