The similarity noted between magnetic poles and electric charges is that unlike ones:
ARepel, and like ones attract
BBoth attract each other
CBoth repel each other
DAttract, and like ones repel
Answer & Solution
Correct answer: D. Attract, and like ones repel
1. The comparison between magnetism and electrostatics is drawn directly.
2. Two north poles brought together push each other apart.
3. A north and a south pole instead pull together.
4. Note the similarity with electrostatics: unlike charges attract and like charges repel.
5. Magnetic poles follow the same pattern.
