Activity 11.6 Class 8 Science
· Take a pair of bar magnets.
· Place the longer side of one of the magnets over three round-shaped pencils or wooden rollers as shown in Figure.
· Now bring one end of the other magnet near the end of the magnet placed on the rollers.

| Experiment of magnets - Attraction and repulsion |
Observation and explanation
When the other end (e.g- S pole) of a magnet is brought near the one end (e.g.- N pole), the magnet on the pencils or rollers starts moving towards the magnet in hand. This shows the attraction takes place between the different ends (poles) of magnets.
In the second case, the same end(pole) is brought near the end of the magnet on the roller, then the magnet starts moving away from the magnet in hand. This shows the repulsion takes place between the same ends (poles) of magnets.
Conclusion
The activity shows that like poles of magnets repel each other and unlike poles attract each other.
