Abstract
Natural magnets played the central role in magnetic studies in early days, leading to the Ampère law of a magnetic field, which was discovered by using iron magnets. Characterized as N- and S-poles, magnetic charges were postulated by analogy to electric charges. However, it was only after Heisenberg’s quantum theory (1928) that the origin of magnetism was attributed to correlated electronic spin angular momenta in materials.
