प्रश्न
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.

The split magnet's components will function as two separate magnets. They'll have the North Pole and the South Pole as well. Using a compass or a test of repulsion between newly generated magnets, we may identify the poles of split magnets.
