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.
The most known magnetic metals are iron, nickel, cobalt and gadolinium. cobalt and nickel classically, it's iron AlNiCo (Aluminum, Nickel and cobalt) makes a great magnet.   The iron ore Magnetite is naturally magnetic and has been known since prehistoric times. There are a few types of magnet. STEEL MAGNETS: Steel is an alloy that consists mostly of iron(element) and has a carbon(element) content between 0.2% and 2.1% by weight, deâ¦pending on the grade. Various other alloying elements are sometimes used, such as manganese, chromium, vanadium, and tungsten(elements).
