Everything with iron is magnetic.

• A. True
• B. False
• C. Not always
• D. Depends on temperature

Answer: (A)

Iron carries magnetic moments from unpaired electrons, and in solid form those moments can align into regions called domains. When a magnetic field is present, these domains tend to align with the field, making the material attracted to magnets or easier to magnetize. Because any substance that contains iron has these magnetic moments, it typically exhibits magnetic behavior under the right conditions. So, in everyday terms, something that includes iron will be magnetic or capable of becoming magnetic, which is why the statement is considered true. Keep in mind that the strength of the magnetic response can vary with temperature and the specific crystal structure or alloy, but the basic idea—iron-containing materials have magnetic properties—holds true in common contexts.
