Like magnetic poles repel each other.

• A. They attract
• B. They repel
• C. They do not interact
• D. They merge

Answer: (B)

Magnetic poles interact so that like poles repel and opposite poles attract. When two bar magnets have the same pole facing each other, they push apart because the magnetic fields repel in that orientation. If you swapped to opposite poles facing, they would attract and pull together. This behavior is what the statement describes, so “they repel” is the correct idea. The other possibilities don’t fit because attracting would only happen with opposite poles, “no interaction” ignores the visible force between magnets, and magnets don’t merge into one object simply because they attract.
