Disc magnets (105)
Disc magnets are round neodymium magnets with a high holding force in relation to their size. At Magnetenspecialist, you will find them from Ø2 to Ø80 mm, in grades N35 to N52. Each magnet shows its dimensions, grade, coating, and holding force, allowing you to quickly find the right size. In stock? Then we ship orders placed and paid for on working days before 4:00 PM the same working day.
Which disc magnet should you choose?
How much a magnet holds depends primarily on the diameter and thickness. Choose by application:
| Application | Suitable size | Example |
|---|---|---|
| Model making, sensors, small closures | Ø3 to Ø6 mm | Ø5 x 3 mm |
| Hatches, small cabinet doors, displays | Ø8 to Ø12 mm | Ø10 x 3 mm |
| Light applications without drilling or screwing | self-adhesive, Ø10 to Ø22 mm | Ø10 x 1 mm self-adhesive |
| Cabinet doors, furniture making, campers and caravans, trade show stands | Ø15 to Ø25 mm | Ø20 x 5 mm |
| Mechanical engineering, workshop, warehouse | Ø30 to Ø50 mm | Ø30 x 10 mm or Ø40 x 20 mm |
| Screwable industrial magnet | Ø60 and Ø80 mm with countersunk hole | Ø60 x 25 mm |

What information is provided for each disc magnet?
- Dimensions: diameter and thickness in millimeters
- Grade: N35 to N52. The number indicates the strength class; for the same size, a higher number is stronger.
- Coating: usually NiCuNi (nickel-copper-nickel), in addition to epoxy and versions with rubber or plastic coating
- Holding force: in kilograms or grams, measured on a flat steel plate
- Maximum temperature: 80 °C for standard versions
The holding force is measured under ideal conditions; in practice, the actual holding force is lower. Read how holding force is determined.
Frequently asked questions
How do I know if a magnet is strong enough?
Look at the holding force and be generous: choose a magnet with a holding force at least several times higher than the weight it needs to carry, or use multiple magnets distributed over the surface. A rough, painted, or curved surface reduces the holding force. The Magnet Advisor will calculate it for you.
Can I use disc magnets in jewelry?
Only when hidden, for example as a closure in a piece of jewelry, and not against the skin. The NiCuNi coating contains nickel, which can cause a reaction in people with a nickel allergy.
What is the difference between self-adhesive and non-self-adhesive?
Self-adhesive disc magnets have an adhesive layer, so you can stick them on without drilling or screwing. For heavier loads, choose a non-self-adhesive size that you can glue or mount.
Are disc magnets safe?
Magnets are not toys and should be kept out of reach of children. Keep them away from pacemakers, electronics, and bank cards. Larger magnets can snap together or against metal with force; keep your fingers away.
When will my order be shipped?
