Collection: N52 Neodymium Sphere Magnets (Ball Magnets)
N52 neodymium sphere magnets
These ball magnets roll freely, so each one turns to match its partner's polarity the moment they meet, which makes them a forgiving choice for rotating and articulated builds where a fixed magnet would fight you. Every sphere is N52, the strongest commercial neodymium grade, triple-plated in nickel-copper-nickel, and sold in metric sizes from 2mm to 20mm. Hobbyists reach for them on turrets, ball-and-socket joints, and posable limbs for tabletop miniatures; jewelry and craft makers use them as hidden clasps; and the larger sizes are a staple for classroom magnetism demonstrations.

Ni-Cu-Ni coating: triple-plated for durability
Common uses
- Rotating turrets and articulated joints on models and miniatures
- Ball-and-socket poses and swappable limbs
- Hidden clasps for jewelry, bags, and garments
- Sewing and craft closures
- Science and classroom magnetism demonstrations
- Retail displays and point-of-sale fixtures
Choosing a size
As a rough guide: 2 to 3mm suits small joints and jewelry, 5mm handles most model turrets and medium joints, 8 to 12mm gives a stronger hold for heavier parts, and 16 to 20mm suits display stands and classroom demos. Match the sphere to the weight it needs to hold rather than the largest that will fit.
