4mm dia N35 Neodymium Sphere Magnet Small Magnetic Balls Nickel Plated Tiny Ball Shaped Magnet
- Pack of 10
- 4mm diameter sphere
- Each sphere’s north and south poles are on opposite sides of the sphere

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 0.32kg vertically from the magnetic face when in flush contact with a mild steel surface.
These 4mm spheres are tiny! They are small but surprisingly strong, despite their diminutive size.
