Question

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 1

The relative strength of the magnetic field is shown by the degree of closeness of the held lines. The degree of closeness is more at X than at Y. Therefore, the field is stronger at X where the field lines are crowded.
