Which term describes a magnet's ability to attract iron-containing materials?

• A. Capacitance
• B. Inductance
• C. Magnetism
• D. Ohm

Answer: (C)

Magnetism describes a magnet’s ability to attract iron-containing materials. This force comes from the magnetic field the magnet produces, which can align the magnetic domains in iron and pull it toward the magnet. The other terms relate to electrical properties: capacitance stores electric energy in a field, inductance involves opposing changes in current due to magnetic effects, and ohm is a measure of electrical resistance. So, the attraction of iron is due to magnetism.
