Introducing our custom small neodymium N52 ring magnets, where maximum magnetic strength meets ultra-compact design.
These precisely engineered magnets pack the full power of N52 grade neodymium into a ring form factor.
So small that it measures just millimeters in diameter and less than 1mm in thickness.
Key Features:
- Ultra-compact ring shape: diameter of just several millimeters
- Incredibly thin profile: less than 1mm thick
- Premium N52 grade neodymium (NdFeB) material for unparalleled magnetic strength
- Precision-manufactured to maintain powerful properties despite minimal size
- Customizable inner and outer diameters to fit your exact specifications
- Multiple magnetization direction options available
To visualize their tiny size:
- Thickness less than that of a credit card
- Diameter smaller than a standard pencil eraser
- Several could fit on a dime with room to spare
From miniature motors and micro-speakers to advanced medical devices and cutting-edge sensor technology.
These tiny N52 ring magnets provide exceptional magnetic fields in an incredibly small package.
Their unique ring shape offers versatility for applications requiring a center clearance or axial magnetic field distribution.
