MAGNET MADNESS
... Magnetic forces are created by the movement of charged particles like electrons (intimately related to electricity). The greatest evidence of magnetism is the attractive or repulsive force observed to act on iron, cobalt and nickel. Similar, more subtle, effects of magnetism are found in all matter ...

Atomic epn(ep) Spin Models and Spectral Lines
... The discharge of hydrogen or helium is not the pure interference like coherent wave. Since hydrogen and helium are gases, they make line spectra through discharge in the quartz cylinder. To make the line spectra the mixing among the discharges of atoms may occur. The optical interference is composed ...

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.
