  Magnetic field lines are shown in the given diagram. A student makes a statement that magnetic field at X is stronger than at Y. Justify this statement. Also redraw the diagram and mark the direction of magnetic field lines. 

Answer:

                  Two magnetic lines of force never intersect each other. If the lines intersect, then at the point of intersection, there would be two directions (the needle would point towards two directions) for the same magnetic field, which is not possible.
