(a)
Draw the pattern of magnetic field lines around a bar magnet. Mark the position of North Pole, South Pole and the places where the magnetic field is strongest.
(b)
Why do the magnetic field lines not intersect each other?
Marking-scheme solution
(a) • Field lines around a bar magnet.
Position of North pole, South pole- to be marked in the diagram
Field is strongest where lines are crowded / at Poles / or indicated in the diagram.
(b) If two field lines cross each other then at the point of intersection, the compass needle would point towards two directions which is not possible.
