The Electron Spin Quantum Number Lab – Diamagnetic Levitation
In this chapter, we discussed the differences between diamagnetic and paramagnetic material. In this lab, we suggest demonstrating how a diamagnetic material is slightly repelled by a magnetic field.
A thin sheet of pyrolytic graphite
A set of magnets
A complete diamagnetic levitation kit can be bought from certain school supply websites. A reasonably priced kit can be found at http://www.teachersource.com/ElectricityAndMagnetism/ElectricityAndMagnetism/DiamagneticLevitationKit.aspx
Place the graphite above the magnets and watch it float!
