Neodymium N52 - High Grade. N42 40 x 20 x 10mm large Strong Neodymium block magnets MRO DIY science VAR PKS.

In a size for size comparison an N45 grade magnet will have approximately 15% ore pull than an N35 grade magnet. Length: 40 mm (1.57). Width: 20 mm (0.78). Thickness: 10 mm (0.39). Axially Magnetised through the thickness so that one 40x20mm face is north, the other is south.

Maximum Temp: 80°C / 176°F. Theoretical Maximum Pull: 44.3lb / 709oz / 20096g. Calculated Max Vertical Hold-guidance only: 8.86lb / 141.8oz / 4019g. This is a seriously powerful magnet and is totally unsuitable for children.

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. Serious risk of soft tissue injury if skin is trapped between magnet and steel or two magnets. These are ideal for use in wind turbines - number of blocks required as below. 1200 Turbine 1.2metre, 4foot (12V/24V/48V) - 8 blocks required. 1800 Turbine 1.8 metre/6foot (12V/24V/48V) - 8 blocks required.

2400 Turbine 2.4 metre/8foot (12V/24V/48V) - 24 blocks required. 3000 Turbine 3.0 metre/10foot (12V/24V/48V) - 24 blocks required. 3600 Turbine 3.6 metre/12foot (12V/24V/48V) - 32 blocks required. 4200 Turbine 4.2 metre/14foot (12V/24V/48V) - 32 blocks required. They are also great for a range of science experiments and for MRO and DIY applications. 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. Serious risk of soft tissue injury if skin is trapped between magnets or magnet and steel.

THIS IS NOT A TOY. We specialise in magnets and magnet related products. All our products are of the best quality and we always sell at wholesale prices.

Items ordered, and paid for, by 12.00 noon Monday-Friday are dispatched on the same day. In small or large quantities. In NdFeB (Neodymium), SmCo (Samarium Cobalt), AlNiCo (Alcomax) and Ceramic. Please note that our products often appear to be'overpacked'.

This is because we are obliged to ensure that not only is there is no damage caused to the magnets during transit but that the magnets do not cause damage to electronic equipment which may also be in transit. Where an item weighs in excess of 2kg the overseas postal rates have not been given and will have to be quoted for seperately. These destinations are blocked from purchasing our listings.
