Show answer and solution
Answer: (A) 1 only
Magnetic field lines have no beginning or end, so they form closed loops; statement 1 is correct. Outside the magnet they run from north to south, but inside the magnet they complete the loop by running from the south pole to the north pole, so statement 2 is wrong.
