Looking for a 10 mm magnet? In magnet catalogs, “10 mm magnet” can mean a 10 mm diameter disk, a 10 mm outside-diameter ring, or a block or rod with one 10 mm dimension. Ten millimeters is approximately 0.394 inch.
Radial Magnets stocks multiple neodymium magnets built around the 10 mm size, including disks, rings and blocks. Use the table below to compare common options, then open the individual product page for complete specifications and current availability.
10mm Diameter Neodymium Magnets
For most buyers searching “10mm magnet,” the most common intent is a round magnet approximately 10 mm in diameter.
| SKU | Shape / Size | Grade | Coating | Listed Pull Force |
|---|---|---|---|---|
| 9771 | Disk — 10 mm × 2 mm | N35 | Ni-Cu-Ni | 2.34 lb |
| 9618 | Disk — 10 mm × 3 mm | N35 | Ni-Cu-Ni | 3.51 lb |
| 9122 | Disk — 10 mm × 5 mm | N35 | Ni-Cu-Ni | 5.84 lb |
| 9403 | Disk — 10 mm × 10 mm | N35 | Ni-Cu-Ni | 11.66 lb |
The pull-force values above are catalog values for the listed parts. Actual force in an application depends on the target steel, contact area, air gap, surface finish, alignment and magnetic circuit.
10mm OD Ring Magnet
If the application needs a center hole, Radial also carries SKU 9711, an N35 neodymium ring magnet with 10 mm OD × 4 mm ID × 3 mm thickness. It is axially magnetized and has a listed pull force of 3.04 lb.
Need a different bore, thickness or grade? Browse neodymium ring magnets and other stock ring sizes by outer diameter, inner diameter, thickness, grade and pull force.
Blocks and Rods with a 10mm Dimension
Some searches for a “10mm magnet” refer to length, width or thickness rather than diameter. Current Radial options include:
- SKU 9400 — N35 block, 10 mm × 5 mm × 2 mm
- SKU 9623 — N35 block, 10 mm × 4 mm × 2 mm
- SKU 9621 — N35 rod, 3 mm diameter × 10 mm
- SKU 9494 — N35 block, 20 mm × 10 mm × 3 mm
Which 10mm Magnet Should You Choose?
Choose a thin 10mm disk when space is limited
A 10 mm × 2 mm or 10 mm × 3 mm disk is useful when the design needs a low-profile round magnet. These sizes are common in sensors, closures, fixtures, small assemblies and prototypes.
Choose a thicker 10mm disk when more magnetic volume is needed
Increasing thickness can increase usable magnetic performance, but the gain depends on the complete magnetic circuit. A thicker magnet is not automatically the best choice if the application has a large air gap, small target or strict weight constraint.
Choose a 10mm ring when you need a center hole
Ring magnets can accommodate shafts, fasteners or mechanical features. Most stock rings are axially magnetized, but the required field direction should always be confirmed. Compare stock Ring Magnets first; if the application needs diametric, radial or multipole magnetization, see What Is a True Radial Magnet? and our diametric vs. radial magnetization guide.
Choose a block or rod when the geometry matters more than diameter
For linear sensors, compact fixtures or rectangular assemblies, a 10 mm dimension may be more useful in a block or rod than in a round disk.
10mm Magnets for OEM and Production Programs
If a stock 10 mm magnet is close but not exact, Radial Magnets can source custom dimensions, grades, coatings and magnetization patterns for production applications. Use the Magnet RFQ Builder for an engineered requirement or the Bulk Magnet RFQ for larger quantity and BOM sourcing.
For production qualification, review our Quality & Compliance capabilities and Magnet Compliance Document Center.

10mm Magnet FAQ
How big is a 10mm magnet in inches?
Ten millimeters is approximately 0.394 inch, slightly larger than 3/8 inch.
Are all 10mm magnets the same strength?
No. Strength varies with material, grade, thickness, shape, magnetization direction and the magnetic circuit. Two magnets with the same 10 mm diameter can have very different pull force and field behavior.
What is the strongest 10mm magnet?
There is no single “strongest” 10 mm magnet without defining the complete geometry and test condition. In the current Radial 10 mm-diameter N35 disk family, thicker versions contain more magnetic material and have higher listed pull-force values, but the best choice depends on the application.
Can Radial make a custom 10mm magnet?
Yes. Custom 10 mm magnets can be specified by material, grade, thickness, coating, tolerance and magnetization pattern. Submit the dimensions and application requirements through the RFQ Builder.
