Product Description
The N52 Neodymium Disc Magnets: 30mm x 4mm Rare Earth (SKU MAGNET-DISC-30MMX4MM) are flat, round rare earth magnets made for industrial and professional use.
Reading the spec
- N52: a high grade of neodymium. Neodymium is the strongest common permanent magnet material, and N52 sits at the top of the grade scale.
- 30mm diameter: 3cm across. That gives a broad, round contact face rather than a small point of grip.
- 4mm depth: a slim disc. It suits places where there is little room behind the thing being held.
What else you need
A magnet only holds to something. Neodymium grips ferrous metal, meaning iron or steel. It will not hold to aluminium, brick, wood or plastic on its own.
This is the magnet alone. Any bracket, housing or adhesive you want to pair it with is separate.
Handling
Strong neodymium discs pull together quickly and can pinch skin. They are also brittle, so let them close slowly and never let two snap together. Keep them away from pacemakers and from bank cards.
