Essentially, diamagnetic behavior is the … WebIt is known that graphite possesses a high specific susceptibility, which according to the most recent measurements of Vaidyanathan with carefully purified samples, is -5·1 × 10-6, that is ...

WebPyrolytic graphite is more diamagnetic than bismuth, but only in the direction perpendicular to the sheets of carbon. In other directions, it is still diamagnetic, but not as good as bismuth. Because the density of pyrolytic graphite is lower than bismuth, (the specific gravity is 2.1), it is light enough to be levitated above a sufficiently ... WebThe diamagnetism of the graphite is high at the direction perpendicular to the plane. The single defect present in the layers causes graphite to behave as magnetic dipole. Graphite is anisotropic in nature so it has high magnetic susceptibility. Pure graphite cannot exhibit ferromagnetic property. The presence of some iron-rich impurities in ...
