Magnetite Vs. Meteorite
Another reason why magnetite is mistaken for meteorites is due to its magnetism. Both meteorites and magnetite attract metal, so it is necessary to use another test like a streak test to tell them apart. Very few meteorites will not attract a magnet. A magnetite's magnetism is considered weak, but it is strong enough to attract large nails.
