Whenever two electrons are paired together in an … Paramagnetism is a form of magnetism whereby some materials are weakly attracted by an externally applied magnetic field, and form internal, induced magnetic fields in the direction of the applied magnetic field. In contrast with this behavior, diamagnetic materials are repelled by magnetic fields and form induced magnetic fields in the direction opposite to that of the applied magnetic field. Paramagnetic materials include most chemical elements and some compounds; t…

WebThe spin of the complex is captured in the S quantum number. S is related to the magnetic moment by: μ = g [S (S+1)] ½ μB. g ~ 2 (fundamental constant for free electrons); μB = Bohr magneton. Since each unpaired electron has S = ½. If n = the number of unpaired electrons, then S = n/2. Then, μ = g [n/2 (n/2+1)] ½ μB.
