Dimensions Ø 20mm (Diameter) x 5mm (Thickness) The dimensions of the product are measured in metric units, with an approximate "tolerance" (manufacturing margin of error) of +/- 0.05mm
Pull Strength: 7.8kg The approximate force (in metric units) required to remove a magnet from industry-standard 3mm thick mild steel. These "strengths" are measured using mathematical calculations, and should be used as a general guide only.
Direction of Magnetism: "Axially" magnetised (top to bottom) thru 5mm thickness. The axis through which a product is magnetised.
Gauss: 2,989 Gauss A measurement of surface "magnetic induction" (B), equal to one ten-thousandth of a Tesla. Gauss indicates the number of lines of magnetic flux per square centimetre, under the CGS metric system.
Grade: N42 In permanent magnets, the grade refers to the materials used in the production process. Material "grades" range from low end (weaker) to high end (stronger). See more about magnet grades at our Help Centre.
Features:- Powerful Rare Earth (Neodymium) permanent magnet.- High gloss Nickel coating, for protection against corrosion.- North pole dent for manufacturers to identify the product's North pole. - Maximum operating temperature 80°C / 100°C
