Although other metallic minerals may mimic magnetiteâs color, luster, hardness and specific gravity, magnetite is the only common mineral that is magnetic. So a magnet is usually all that is needed to identify its presence. Magnetite crystals usually only occur when magma cools slowly enough for crystals to form and settle out of the magma.
Now I need to go down to the fridge for a magnet to check!!! I'll be back... Magnetic metals are those that can be attracted by a magnet and can also form a magnet when magnetised. These metals are iron, nickel, cobalt, gadolinium, neodymium and samarium. Some of these metals are rare but are magnetic and form a magnetic field which in turns transforms them to permanent magnets.
