Guy's Magnets 10 mm x 3.5 mm x 2.4 mm PN10 bonded neodymium block

Length: 10 mm (0.39") Width: 3.5 mm (0.13") Thickness: 2.4 mm (0.09") Axially Magnetised through the thickness so that one 10x3.5mm face is north, the other is south Weight: 0.504g Grade: NB10 (Bonded Neodymium) Maximum Temp: 80°C / 176°F Theoretical Maximum Pull: 0.62lb / 9.9oz / 280g Calculated Max Vertical Hold-guidance only: 0.12lb / 1.9oz / 56g WARNINGS: All neodymium magnets are unsuitable for children; do not ingest. 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.

Guy's Magnets 3 mm x 3 mm x 1mm N52 neodymium block

+/-0.1mm manufacturers tolerance on any dimension Magnetised through the thickness so that one 3x3mm face is north and the other is south

Guy's Magnets 8mm x 3mm x 1mm N52 High Grade neodymium block

+/-0.1mm manufacturers tolerance on any dimension Magnetised through the thickness so that one 8x3mm face is north and the other is south

Guy's Magnets 3 mm x 3 mm x 20 mm neodymium block

+/-0.1mm manufacturers tolerance on any dimension Magnetised through the length so that one 3x3mm face is north and the other is south Note the pull and hold calculations are from the mathematical formula for this grade.  This does not take account of the fact that they can be more easily removed than expected as the length acts as a lever.
