Abstract

A first example of a two-state quantum system is an ensemble of independent spin-\(\frac{1}{2}\) particles, electrons, for instance, interacting with an external magnetic field via their magnetic dipole moment. We discuss the potential energy of the magnetic dipole interaction and recall the basic experiments that discovered the quantization of energy and angular momentum.
