It has a spin I of 1/2 and when placed in a magnetic field of strength B 0 it will occupy 2I + 1 quantized magnetic energy states, in this case 2. The relative populations of these states, termed Zeeman levels, are normally given by a …
Web8 aug. 2024 · You can determine whether the net effect in a sample is diamagnetic or paramagnetic by examining the electron configuration of each element. If the electron subshells are completely filled with electrons, the material will be diamagnetic because the magnetic fields cancel each other out. If the electron subshells are incompletely filled, … Diamagnetism appears in all materials and is the tendency of a material to oppose an applied magnetic field, and therefore, to be repelled by a magnetic field. However, in a material with paramagnetic properties (that is, with a tendency to enhance an external magnetic field), the paramagnetic behavior dominates. Thus, despite its universal occurrence, diamagnetic behavior is ob…
