Diamagnetism and nuclear spin
WebParamagnetism is the orientation of the magnetic moments of the atoms in the direction of the applied magnetic field (Fig. 8.7 ). Paramagnetism is also a weak phenomenon and the effect of diamagnetism in the material needs to be also considered to determine its net response to an external magnetic field. The main difference between materials ... Web1.2.1 Diamagnetism. In most diamagnetic materials, atoms have an even number of electrons in the partially filled shells, so that the major magnetic moments are due to …
