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.
A ferromagnetic material is one that has magnetic properties similar to those of iron. In other words, you can make a magnet out of it. Some other ferromagnetic materials are nickel, cobalt, and alnico, an aluminum-nickel-cobalt alloy. Magnetic fields come from currents.
