Ștefan Procopiu – The Universal Scientific Heritage of a Romanian Scientist

The scientific heritage of Ștefan Procopiu (1890–1972), reputed physicist, educator and member of Romanian Academy has an international dimension. His scientific works, reflected in a series of discoveries, opened new directions of research in physics, such as: depolarization of light through the suspension of crystalline particles (Procopiu’s phenomenon), the circular effect of demagnetization discontinuity manifested when an alternative electric current flows through a ferromagnetic wire (Procopiu’ effect – inverse Wiedemann effect), calculation of the magnetic moment of the electron (Bohr-Procopiu magneton), the first systematic measurement of terrestrial magnetism in Eastern Europe.
