Abstract
In the application of magnetic etching as a metallographic tool, we should be aware that magnetism is, in its most basic form, an atomic phenomenon.* The atoms in most materials have electrons that are paired and spinning in opposite directions so that the net magnetism is cancelled. In some materials, however, there are atoms with one or more unpaired electrons, and these produce a net magnetic moment.
