Afrom south pole to north pole
Bfrom both poles to the middle
Cin no fixed direction
Dfrom north pole to south pole
Answer & Solution
Correct answer: D. from north pole to south pole
1. By convention field lines emerge from the north pole and enter the south pole outside the magnet.
2. So outside the magnet they run **from north to south** (and from S to N inside).
3. Field lines never cross one another.
