- gnfargbl 3y agoNo, but if you can find a strong enough magnet then it might be possible to levitate one using diamagnetism. Big magnet, though. One estimate [1] puts it on the order of 10T. That's a lot of engineering just to play a Dracula prank on someone.

- username135 3y agoSo you're saying there's a chance?
- HelloNurse 3y agoThere's a straightforward physical theory: colossal magnetic fields + slightly diamagnetic materials (including a human body with small superconducting particles) = magnetic levitation. But human bodies might contain paramagnetic and ferromagnetic particles too, and more importantly building magnets that are strong enough to levitate a corpse is an expensive and difficult engineering challenge.
