Dangerous Magnets Ltd is your helpful & reputable source for incredibly strong neodymium magnets

- Magnets can pinch skin and cut clothing.
- For sensitive devices (e.g. credit cards, pacemakers, magnetic recording), keep at a distance where the field is negligible.

- This specialised construction consists of a magnet enclosed in a steel “pot”, or "cup". This concentrates the magnetic field to a narrow ring area on the countersunk side of the unit.
- The highly-localised field pulls very well to flat, smooth steel, eg a washer or thin sheet steel, but 4mm steel needed for maximum pull.
- Not so suitable for pulling from a distance, and unsuitable pulling towards another magnet. Use our standard magnets for these applications.
- Pull is not lost when set into a steel surface.
- More protected against chipping than standard magnets (but do not over-tighten mounting screw)
- Although this type has its pros and cons for some applications, it is about half the price of an equal strength "standard" magnet.

- Pack of 2 magnets. (Extras by arrangement at same per-magnet price)
- Dimensions: 42mm diameter, 9.1mm thick, with 6.4mm countersunk hole for #8, #10, or #12 self-tapping mounting screw.
- Neodymium magnets are about 10x more powerful than traditional magnet materials.
- Holding Force: In ideal circumstances, i.e. to 4mm flat steel, approx 37kg for each magnet. Resistance to sliding is about 1/3 that, depending on the friction with the surface.
- The finish is durable Nickel/Copper/Nickel plating.
- Not suitable for motors, etc.

- Securely close gate etc. (Weather protection advisable.)
- Hold fittings to steel walls, trucks, heavy machinery etc.
- Where stray magnetic fields must be kept to a minimum.
