If you've seen the photo of the levitating frog swimming in a pool of water in mid-air, then you've seen diamagnetic levitation, based on a system of high-energy electromagnets in a lab environment.
Experimenter Jeremiah Hansen is doing something similar, but using only low-powered permanent magnets! The trick is using pyrolitic carbon, a naturally diamagnetic form of charcoal that levitates over a permanent magnet without any tricks or fancy equipment. It's an exciting experiment to watch, and a great way to impress your science teacher, who probably hasn't heard about this weak-diamagnetic form of levitation before now!If you've seen the photo of the levitating frog swimming in a pool of water in mid-air, then you've seen diamagnetic levitation, based on a ...all »If you've seen the photo of the levitating frog swimming in a pool of water in mid-air, then you've seen diamagnetic levitation, based on a system of high-energy electromagnets in a lab environment.
