Ferrous metals commonly exhibit which property?

• A. They are non-magnetic
• B. They are highly resistant to corrosion
• C. They are magnetic
• D. They are transparent

Answer: (C)

Ferrous metals contain iron, and at room temperature they are typically magnetic. This comes from ferromagnetism, where tiny magnetic domains within iron align in a magnetic field, making the metal attracted to magnets. That magnetic behavior is the property most characteristic of ferrous metals, which is why it’s the best description among the options. In contrast, they aren’t inherently highly resistant to corrosion (they rust unless coated or alloyed, as in stainless steel), and metals are not transparent.
