What metals are magnetic?
Ferromagnetic metals are strongly attracted to a magnetic force. The most common metals used as magnets include iron, nickel, and cobalt. Rare earth metals like neodymium, gadolinium, and samarium also have strong magnetic properties.
Any alloy composed of ferromagnetic materials can also attract magnets. For instance, stainless steels with high concentrations of iron are magnetic. Other examples of ferromagnetic alloys include chromium and alnico.
Metals that have a weak attraction to magnets are called paramagnetic materials. Magnesium, lithium, and molybdenum are a few examples of these. Their attractive force is significantly weaker than that of ferromagnetic metals.
