Magnets are found everywhere: In doors and drawers, in toys and tools, at friges and pinboards, in households, offices and workshops. Magnets are an invitation to children to make their own experiences, to become little explorers and discoverers. Magnets – the right ones! – are easy to handle, there is no need of complicate experimental setup, and magnetic effects are amazing.

Children have to be curious. And they shall detect the fascinating world of magnetism. But nevertheless: Magnets are no toys. Don’t leave your children alone. Especially neodymium magnets in most cases are too strong for a child’s hands. If swallowed magnets can cause danger of life! Please read our safety precautions. Children should not make their first experiences with neodymiums but with magnets of AlNiCo and ferrite and our special collection of science and educational magnets.
