All you need to levitate pyrolytic graphite.
Four 12mm gold plated Neodymium Iron Boron magnets
One piece of Pyrolytic Graphite.
Trim up the graphite as explained in the pyrolytic graphite levitation section, and it will float above the magnets like magic.
CAUTION: Neodymium magnets are so powerful that they will break if allowed to jump together. Work with them on a steel surface to prevent jumping.
