  • +/-0.1mm manufacturers tolerance on any dimension
  • Magnetised through the thickness so that one flat face is north and the other is south

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.

These magnets, like all rods, are great as reed switches.

N42 is approximately 18% stronger, in a size for size comparison to N35.
