Everyone’s favourite magnet! This 7 mm magnetic sphere is nickel-plated and ideal for experiments and combining with other magnets. Once you’ve held them in your hands, you won’t want to put them down. These small but very powerful super magnets inevitably arouse a sense of play. The more, the better.

Thanks to a slightly thicker coating, nickel-plated magnets are better protected against abrasion than zinc-plated magnets.

Caution: Due to the dangers involved when magnets are swallowed, these small magnetic spheres (like all super magnets) are not suitable for children under the age of 14. Swallowing two or more magnets can be fatal. Although these spherical magnets are being advertised and sold as toys in many places on the internet, please heed this warning and keep the magnets out of the hands of children.
