A bar magnet is cut into two pieces A and B, from the middle, as shown in Fig. 13.8.


Will the two pieces act as individual magnets? Mark the poles of these two pieces. Suggest an activity to verify your answer.

When we break a magnet into two halves lengthwise these dipoles get separated and act as individual magnets.


So, yes the two pieces will act as individual magnets.


The poles of new magnets can be detected by using a compass or by test of repulsion between newly formed magnets.


So new poles are marked as:
