Question

ix. how could 3 magnets be arranged end - to - end so that there will be no attraction between them? a. n s s n n s b. s n n s n s c. n s n s s n d. s n s n s n

Explanation:

Magnetic poles follow the rule: like poles repel, opposite poles attract. To have no attraction between end-to-end arranged magnets, adjacent poles must be like poles (so they repel, not attract). We check each option:

• Option A: Adjacent poles are S-S, N-N (like poles, no attraction)
• Option B: Adjacent poles are N-N, S-N (opposite poles attract)
• Option C: Adjacent poles are S-N, S-S (opposite poles attract)
• Option D: Adjacent poles are N-S, N-S (opposite poles attract)

Only Option A has all adjacent like poles, so no attraction occurs.

Answer:

A. [N S] [S N] [N S]
