Explain quantitatively the order of magnitude difference between the diamagnetic susceptibility of N2 (~5 X 10-9) (at STP) and Cu (~10-5). The derivation of Langevin's susceptibility relies on the assumption that the material has a classically bound electron (rotating around an atom to create the magnetic moment), however, metals do not have localized electrons. Susceptibility is nearly temperature independent. Using this characteristic, it is possible for the A negative magnetization is produced when the material is exposed to external magnetic field, thus the susceptibility is negative.
