Abstract:
In the laboratory, the Einstein-de Haas effect proves that a change in the magnetic moment (μ) of a body results in a proportional change in its mechanical angular momentum (L). This is governed by the gyromagnetic ratio (γ). History records a profound moment of tension during the initial 1915 experiments. The results consistently produced a torque that was exactly twice the value predicted by classical orbital models. Einstein, tethered to a burgeoning geometric model that viewed bodies as passive participants in space-time curvature, initially struggled with this result, as it suggested a mechanical reality that his geometry could not account for. To save the geometric model, physics eventually "labelled" this discrepancy as the anomalous g-factor, attributing it to an abstract "quantum spin."
