Superconducting material can become pinned in place above a neodymium magnet. When those magnets are arranged in a track, the superconductor can follow that track even if it has loops and corkscrews.
Hi, /m/brainfood! I'm Hitstun from /m/FloatingIsFun where we're easily distracted by things that float in the air. My brain's happy when my focus gets to wander around in three dimensions. I thought you'd like some flux pinning, so I posted it here too. We get a lot of fantasy illustrations, but the rare real-life examples of floating are very much appreciated. Feel free to post some there yourself as long as you credit its creator in the title and link to your source in the comments.
