The importance of iron ore to human society should be obvious, but magnetite has also played a subtler, but equally important, historic role in human civilization. Early on, people discovered that striking magnetite ‘lodestone’ against pieces of iron would magnetize the iron. This magnetized iron was used to make the first compasses, which ...
