They are very small as advertised. Due to their small size, they had a weak magnetic force, making it difficult for students to see the magnetic field. This allowed the children to explore different magnets. After learning about attraction and repulsion, they were able to test and mark the poles on different magnets, enhancing the visual experience. Update: Over 150 children have used these magnets and have been dropped, stepped on and abused. You're still on the beat. I am changing my rating from 4 to 5 stars
