Neodymium Rare Earth Ring Magnets
All neodymium rare earth ring magnets are magnetized such that the north and south poles are on the flat surfaces.
Each can be used to build a simple loudspeaker. You can also use them to retrieve metallic objects by tieing a string around them.
We currently do not list holding forces for ring magnets but you can estimate them by comparing to disc magnets & subtracting the volume
of the hole from the volume of the entire disc.
- nickel-copper-nickel coated
- size tolerance for dimensions <10mm: +/- 0.05mm
- size tolerance for dimensions >10mm: +/- 0.1mm
- magnet strength variance piece to piece: <8%
- 80C maximum operating temperature
- axis of magnetization is perpendicular to page
