These 5mm magnetic balls spheres magnets are tiny! They are small but surprisingly strong, despite their diminutive size.

These precision neodymium sphere magnets are available in either 3mm or 25mm diameter. They are commonly used in sculptures, artistic displays and experiments. The power of these magnets should not be underestimated; there is a risk that these magnets will chip and break if they are allowed to slam together. Because of this they are not suitable for children and should not be bought as toys.

Magnetic spheres are mainly used for creative applications rather than manufacturing or engineering purposes. They make great accessories for artists and designers who use them for creative displays. Despite their relatively small diameter each magnet can still support an astonishing 0.4 vertically from the magnetic face when in flush contact with a mild steel surface.
