Rare earth magnets are fascinating things, both in their capabilities and their history. Magnetism itself, or rather, the human discovery and understanding of magnetism, dates back to around 600 BC. Back then, Greek philosophers noted some peculiar properties of some natural ferrite stones. Aristophanes was the man who discovered the phenomenon of electrical charge, although we did not further our understanding of this for nearly two thousand years afterwards. It was finally around 1600 AD that the term “electric” was coined.
