Question

Which of the following is NOT a property of magnetic lines? A. magnetic field lines are dense near poles B. magnetic field lines are closed loops C. magnetic field lines intersect each other D. magnetic field lines emerge from north pole and merge at the south pole​

Answer 1

Answer:

These lines do not intersect, because if they do so then it would mean two value of magnetic field at a single point, which is not possible. At the poles of the magnet the magnetic field is stronger because the lines of force there are crowded together and away from the poles the magnetic field is weak.
