- +/-0.1mm manufacturers tolerance on any dimension
- Magnetised through the thickness so that one flat face is north and the other is south
- The pull and hold figures are purely based upon mathematical formulae and are for guidance only and must not be relied upon
N52 is the highest grade / strongest grade currently widely available.
The length of the magnet means that it very easy to TIP it to it's edge to remove it and, therefore, the pull and hold will feel significantly less than the calculation figures shown.
The pull is calculated using a mathematical formula and is, therefore, the theoretical maximum hold between one magnet and a mild steel plate. It does not take account of manufacturing tolerances, plating, plating thickness or variances in a mild steel plate. The vertical hold is based upon the calculated pull and is, therefore, only for guidance. Factors such as paint thickness, plasticised surfaces, movement and vibration are not taken into account.
WARNING: Neodymium magnets are unsuitable for children under 8. All neodymium magnets are brittle. Do not allow these magnets to jump together or to an iron/steel surface - they will break, crack, chip or shatter. Thin neodymium magnets DO NOT FLEX, if you attempt to flex them they will snap in half. THIS IS NOT A TOY. DO NOT INGEST
