Steel ball, diameter: 12.7 mm (4 pcs)
 
The 12.7 mm steel balls come in a set of 4 and are suitable for magnetic demonstrations, educational experiments, simple technical applications and DIY projects.
 
Steel balls clearly demonstrate magnetic attraction, force distribution at contact points and the behaviour of ferromagnetic components. With a suitable magnet, chain-like arrangements and simple motion experiments can also be demonstrated.
 
Near strong magnets, small metal parts can snap together suddenly, so careful handling is required. This product is not a toy for young children.
