1. A spinning charge generates a magnetic field, as shown by the animation on the right. The resulting spin-magnet has a magnetic moment (μ) proportional to the spin.2. In the presence of an external magnetic field (B 0), two spin states exist, +1/2 and -1/2.The magnetic moment of the lower energy +1/2 state is aligned with the external field, but that of the higher energy -1/2 spin state is

The maximum number of unpaired electrons is 7, in Gd 3+, with a magnetic moment of 7.94 B.M., but the largest magnetic moments, at 10.4–10.7 B.M., are exhibited by Dy 3+ and Ho 3+. However, in Gd 3+ all the electrons have parallel spin and this property is important for the use of gadolinium complexes as contrast reagent in MRI scans

In analogy with other methods of separation based on physical properties, magnetism can be used for separating materials which respond more strongly to a magnetic force from other materials which exhibit a less strong response. In any given separation it is customary to describe the two products as “magnetic” and “nonmagnetic” respectively
