Bohr–van Leeuwen Theorem
A theorem independently derived by Niels Bohr and Hendrika Johanna van Leeuwen, proving that within the framework of classical statistical mechanics the macroscopic magnetization of any material in thermal equilibrium must be zero. The theorem demonstrates a fundamental inability of classical physics to account for magnetic phenomena.
