    Introduction The Einstein-de Haas effect is a physical phenomenon that demonstrates the connection between the angular momentum and the magnetic moment of a ferromagnetic material. It provides experimental evidence for the idea that spin angular momentum is indeed of the same nature as the classical angular momentum. The Basic Principle of the Einstein-de Haas Effect…
