When a second south pole is brought near the south pole of a magnet, how are the field lines affected?

• A. Toward the second south pole
• B. Away from the second south pole
• C. Around the second south pole
• D. Through the second south pole

Answer: (B)

Field lines show the direction and strength of the magnetic field, flowing from north to south. Like poles repel, so bringing a second south pole close to the south end of a magnet causes a repulsive interaction. This repulsion pushes the nearby field lines away from the second south pole, so the lines bend away rather than entering that pole. The result is a lower line density near the second south pole and lines curving around it, rather than being drawn toward or passing through it. This visualizes how the field rearranges under the influence of repulsion between like poles.
