Magnetic attraction principles

Steps:

• N pole attracts S pole of another magnet due to opposite poles.
• Iron is ferromagnetic and becomes temporarily magnetized, attracting to any magnet pole.
• Copper is non-magnetic and experiences no attraction.
• Only iron and S pole attract; copper does not.

Why A is correct:

• Law of magnetism: unlike poles attract, and ferromagnets like iron are drawn to magnetic fields regardless of pole.

Why the others are wrong:

• B and C incorrectly state iron is not attracted, ignoring its ferromagnetic properties.
• D incorrectly states S pole is not attracted and copper is, violating opposite pole attraction and non-magnetic behavior.

Final answer: A
