Important Questions Class 6 Science Chapter 4: Exploring Magnets

Magnets are objects that attract certain materials and show direction-finding properties.
A magnet always has two poles, and a freely suspended magnet rests along the north-south direction.

Magnets help us understand attraction, repulsion, direction-finding and invisible magnetic effects through simple activities.
