    Betty, Hematite is one form of iron oxide, magnetite has two ions of
    iron oxide in its molecular structure (Fe+2 & Fe+3)  This means that
    some of the iron ions have one less electron than the other and they
    arrange themselves into a north-south polarity because of the
    difference in charge between the ions. Hematite is non magnetic
    because it has only one of these ions in its structure. 

    The ancient Chinese used to make compasses using the typical Chinese
    soup spoon configuration and floating the magnetite spoon in
    mercury. They were the first true inventors of the compass, although
    they were not quite sure what to do with it.  It remained merely a
    curiosity for some centuries and passed away as so many things they
    invented did.
