What happens when the north poles of two different bar magnets are brought close together?
AThey attract each other
BThey repel each other
CNo force acts between them
DThey fuse into one pole
Answer & Solution
Correct answer: B. They repel each other
1. Magnetic poles interact similarly to electric charges: like poles push apart, unlike poles pull together.
2. The text states: "the north poles of two different magnets repel each other, and likewise for the south poles."
3. So two north poles brought close together will push each other away, not attract or remain unaffected.
4. "Fusing into one pole" is not a real magnetic phenomenon described anywhere in the text.
