... Each electron in an atom has an orbital magnetic dipole moment and a spin magnetic dipole moment. The resultant of these two vectors combines with similar resultants for all other electrons in the atom, and the resultant for each atom combines with those for all the other atoms in a sample of a mate ...

When a current-carrying loop is placed in a magnetic field
... The magnetic field around a bar magnet is due to the motion of charges, but not the flow of electricity. It is due to the motion of the electrons themselves. The orbit of the electron around the nucleus is like an atom-sized loop of current, in addition the electron spin also produces a magnetic fi ...

Magnetochemistry
Magnetochemistry is concerned with the magnetic properties of chemical compounds. Magnetic properties arise from the spin and orbital angular momentum of the electrons contained in a compound. Compounds are diamagnetic when they contain no unpaired electrons. Molecular compounds that contain one or more unpaired electrons are paramagnetic. The magnitude of the paramagnetism is expressed as an effective magnetic moment, μeff. For first-row transition metals the magnitude of μeff is, to a first approximation, a simple function of the number of unpaired electrons, the spin-only formula. In general, spin-orbit coupling causes μeff to deviate from the spin-only formula. For the heavier transition metals, lanthanides and actinides, spin-orbit coupling cannot be ignored. Exchange interaction can occur in clusters and infinite lattices, resulting in ferromagnetism, antiferromagnetism or ferrimagnetism depending on the relative orientations of the individual spins.
