Ferromagnetic materials are metals that are easily magnetized.

• A. True
• B. False
• C. Sometimes
• D. Not at all

Answer: (A)

Ferromagnetism is the property of materials that respond strongly to magnetic fields and can become magnetized easily. In metals like iron, nickel, and cobalt, magnetic moments tend to align with each other due to exchange interactions, forming regions called domains. When you apply an external magnetic field, these domains grow and align with the field, producing a large net magnetization. Because this alignment can persist, ferromagnetic materials can stay magnetized even after the external field is removed, which is why they’re used to make permanent magnets. In everyday terms, this means ferromagnetic materials are metals that magnetize readily, so the statement is true.
