Twenty 17mm balls - 70c each, and they spin when they repel

20 plastic-covered magnetic balls, 17mm diameter.

The reason to have spheres rather than discs is that a sphere can rotate. Bring two together the wrong way round and instead of just pushing apart they spin to find their own alignment - which is magnetism visibly solving a problem, and it is far more convincing than a diagram of field lines.

Twenty is a top-up quantity: enough for a pair of students to build and chain, and the right thing to buy when the Fun Pack's original twenty have gradually gone behind the cupboard.

Safety - the supplier's warning, in full and unedited: The intended use of these magnets is for educational purposes only. Adult supervision is required at all times. Not suitable for children under the age of 8. Not suitable for craft projects. Seek immediate medical attention if magnets are swallowed or inhaled. These are strong powered magnets and can cause medical issues if digested. These magnets are not a toy and are not intended for early learning centres or younger age groups in school or learning or unsupervised environments.

Why we are not paraphrasing that. Two or more small magnets swallowed separately can attract through the wall of the bowel and cause a perforation. It is a surgical emergency, not a stomach ache. If you are buying for a prep or early years room, buy the large ferrite block or the giant horseshoe instead - both are too big to swallow.

FAQs

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.
Because they rotate. Two spheres brought together the wrong way spin to realign themselves, which shows a child the force doing something rather than just pushing. Discs only push.
Yes - the Fun Pack contains twenty of the same balls, so this is the top-up pack when they go missing.
Strong enough to chain together and to be picked up through a sheet of paper. Strong enough, also, that the ingestion warning is serious - these are the exact size and strength the warning exists for.
No. Twenty small strong magnets in a house with a toddler is the precise scenario the supplier's warning describes. Count them in and out of the room.
