Do like poles repel and unlike poles attract?

Do like poles repel and unlike poles attract?

• A. True; unlike poles repel and like poles attract.
• B. True; like poles repel and unlike poles attract.
• C. False; like poles attract and unlike poles repel.
• D. False; poles have no interaction.

Answer: (B)

The main idea is how magnetic poles interact: like poles repel and unlike poles attract. This is observed when you bring two magnets close. If the facing poles are the same (north-north or south-south), they push apart; if they are opposite (north-south), they pull together. The reasoning lies in the magnetic field lines: lines leave the north and enter the south, so when facing opposite poles the field lines connect smoothly, producing attraction; when facing like poles, the field lines oppose each other, producing repulsion. Also, magnets always come in north and south pairs, since breaking one magnet creates new poles. So the true statement is that like poles repel and unlike poles attract. The other options either say there’s no interaction or state the reverse, which don’t match what’s observed.
