Pyrolytic Graphite Levitation

Levitating pyrolytic graphite wafer over four ND45 magnets.

The levitation effect (as pointed out by a well informed observer and experimentalist) is only observable when there is a sufficient magnetic gradient (north to south) in a proper magnetic configuration. (Thanks Scott of iLevitation)

Pyrolytic graphite (or carbon) is a diamagentic material.

Consequently, diamagnetism is a form of magnetism that is only exhibited by a substance in the presence of an externally applied (strong) magnetic field. It is generally a weak effect in most materials(such as pyrolytic graphite), although superconductors exhibit a strong effect (such as supercooled Yba2Cu3O7 or Bi2Sr2Ca2Cu3O9).

Even a pure Bi rod suspended by a string can be repelled by a ND type magnet. (at room temperature).

Please credit the musicians whose work you use in the video description in the future. In the mean time, what is that lovely song called and who is it performed by?

[clagwell]

@mchenrinson Franz Shubert Sonata in A. No idea who the pianist was as my source didnt provide that info.

Cool video, you might want to add to your description that the levitation effect is only observable when there is a sufficient magnetic gradient (north to south) in a proper magnetic configuration.

You are absolutely right. Good point and thanks !

[Darwinassist]

is the graphite just acting as a simple magnet or is it something different?

[clagwell]

As Wikipedia explains it:

"diamagnetism is a form of magnetism that is only exhibited by a substance in the presence of an externally applied magnetic field."

Putting it simply, no, the graphite is not acting as a simple magnet as it has no poles. The wafer can be flipped over and the results are still the same. The pyrolytic graphite has a unique chemical composition which exhibits a repulsive effect in the presence of a strong magnetic field.

Could this be used for a Maglev somehow?

I wanted to see a piece of paper passed between them. Demonstrate like a magician that there are no strings attached. ;o)

[matthias2986]

something like a mirror? +10 on your explanation sir. now i must find what about its chemical composition appropriates this result! =D

Informative video. Thanks for posting.
