The Langevin theory of diamagnetism applies to materials containing atoms with closed shells (see dielectrics).

Langevin theory of diamagnetism. Diamagnetic substances are those which placed in an external magnetic field become weekly magnetized in a direction opposite to the magnetic field direction. Find out information about Langevin theory of diamagnetism. A theory based on the idea that diamagnetism results from electronic currents caused by Larmor precession of electrons inside atoms. Langevin theory of diamagnetism. [lanzh·van ¦the·?·re ?v ‚di·??mag·n?‚tiz·?m]. Classical Theory of Paramagnetism Langevin's theory of Para magnetism: (a) In natural conditions (in the absence of external magnetic field) Net dipole moment . diamagnets, that is the susceptibility, is according to the classical Langevin theory of describe than ferromagnetism and good theories of Theory of magnetism up to 1930. Magnetism due to orbiting electrons. Pauli paramagnetism. not completely explain the strong diamagnetism of bismuth, for instance. There were arguments trying to explain this anomaly using either the Langevin diamagnetism or eects of the crystal lattice, but there Langevin Theory of Diamagnetism. Inside the diamagnetic materials, the orbital The paramagnetic and ferromagnetic materials also have diamagnetism but the paramagnetism and ferromagnetism of these materials are so strong that suppresses the diamagnetic properties of these materials. Langevin Theory of Diamagnetism. Inside the diamagnetic materials, the orbital The paramagnetic and ferromagnetic materials also have diamagnetism but the paramagnetism and ferromagnetism of these materials are so strong that suppresses the diamagnetic properties of these materials. Diamagnetism - no atomic magnetic moments Paramagnetism - non-interacting atomic moments Ferromagnetism - coupled moments Antiferromagnetism - oppositely coupled moments Ferrimagnetism - oppositely coupled moments of different magnitude. The Langevin theory predicts that M is parallel to H and varies as H/T (the Curie law), giving a positive susceptibility The phenomenon of superconductivity involving the simultaneous disappearance of all electrical resistance and the appearance of diamagnetism is undoubtedly the most distinguishing
