Product Description
The N52 Neodymium Magnets: 20mm x 4mm Rare Earth Disc Set is made up of round rare earth magnets in N52 grade, listed for industrial and precision applications.
What the numbers mean
- N52 is the grade. Neodymium magnets are the strongest permanent magnets in common use, and this listing is for the N52 grade.
- 20mm diameter gives a flat face two centimetres across. That is the area that meets the surface it grips.
- 4mm depth keeps the profile slim, so each disc takes up little space in an assembly.
- Disc shape means the poles sit on the two flat faces.
What you need alongside them
A magnet needs something to act on. That is usually a flat ferrous surface, such as steel, or a second magnet. Plan the fixing method for the disc itself, whether that is a recess or a bonding method suited to your materials.
Handling
Neodymium is brittle and can chip if two discs snap together. Strong magnets can also pinch skin. Keep them away from pacemakers, bank cards and other magnetically sensitive items. Slide discs apart rather than pulling them straight off each other.
