A property of some materials in which there is a force of repulsion or attraction between poles is called what?

• A. Polarization
• B. Electric field
• C. Static charge
• D. Magnetism

Answer: (D)

Magnetism describes the forces between magnetic poles. A magnet has north and south ends, and like poles push away while opposite poles pull together. This behavior arises from the magnetic field generated by aligned microscopic magnetic moments inside the material; when many moments line up, the material exhibits a net magnetic pole at its ends and can attract or repel other magnets or magnetic materials. Polarization involves aligning electric dipoles in an electric field, which is an electric, not magnetic, effect. The electric field is the region around charges where they experience force, and static charge refers to stationary electric charges. So the interaction described by poles attracting or repelling is magnetism.
