Problem
Two identical bar magnets are kept coaxially on a table with their north poles facing each other at a separation of 4 cm.
(i) Draw the combined magnetic field pattern produced by the two magnets.
(ii) Mark and label all neutral points (points where the resultant magnetic field is zero) in your diagram.
(iii) Explain how you identified the positions of these neutral points from your sketch.
(iv) Predict qualitatively what will happen to the positions of the neutral points if the separation between the north poles is reduced to 2 cm. Give reason for your answer.
