This Demonstration deals with the electron-spin alignment dynamics inherent in ferromagnetic material. A persistent macroscopic magnetization is manifested when the material's initial spin densities are such that one of these spin phases is sufficiently greater than the other. The default spin-down density setting of 0.5, which translates to a complement spin-up density of 0.5, therefore rarely manifests any magnetization.
