  • Does pyrite retain the magnetic properties of its element ...

    2015-9-17 · Magnetism is not an inherent property of an element, but that of a compound. Most compounds of iron are not magnetic (though some are); on the other hand, there are organic magnets made out of totally non-magnetic elements. Think of something based on chemical properties instead. Pyrite is a salt of a metal and a weak acid.
