Round Ceramic Magnets 20mm Pack of 100

No, and the supplier says so plainly: not suitable for children under 8, adult supervision at all times, not a toy, and not intended for early learning centres. Two or more small magnets swallowed separately can attract through the bowel wall and cause a perforation - that is a surgical emergency. For under-8s, buy the large ferrite block magnet or the giant horseshoe instead.

These are plain 20mm discs and the marbles are 15mm coloured spheres. Discs stack, which is what you want for testing force through layers; spheres roll and chain, which is better for structures. Both carry the same under-8 warning.

They are standard ceramic classroom magnets - strong enough to demonstrate attraction, repulsion and force through thin materials. For lifting, the giant horseshoe (1.8kg) is the one.

Because magnetism is taught by everyone testing things at once, not by watching. A hundred covers a class in pairs with spares for the ones that end up behind a cupboard.

We would not. They carry an under-8 ingestion warning and the risk in a home with younger siblings is exactly the situation the warning is about. Keep them counted in and out of the classroom.
