Answer:
But if the two magnetic field lines intersect one another, then the resultant force on a North Pole placed at the point of intersection will be along to directions, which is not possible. (b) Magnetic field lines are closed curves or forms a closed loop. This is because two magnetic field lines can never intersect.
