Which statement best describes the path of magnetic lines of force relative to poles?

• A. They connect opposite poles, forming loops.
• B. They connect identical poles.
• C. They do not connect poles at all.
• D. They only exist inside the magnet.

Answer: (A)

Magnetic lines of force always form closed loops. They originate at the north pole and terminate at the south pole, outside the magnet. Inside the magnet the direction reverses, going from south back to north, so the entire path forms a loop that connects opposite poles. This is why the statement describing lines connecting opposite poles and forming loops is the best description. They don’t connect identical poles, and they exist both inside and outside magnets.
