30mm x 1mm Disc - N42 (Rare Earth)

Please note: This is an extremely thin and fragile neodymium magnet. While it is very strong for its size, it can crack or shatter if dropped, impacted, or allowed to snap together. We take great care to package magnets securely for transit; however, due to the brittle nature of thin magnets, breakages are not covered under warranty.

Dimensions: Ø 30mm (Diameter)  x  1mm (Thickness) 
The dimensions of the product are measured in metric units, with an approximate "tolerance" (manufacturing margin of error) of +/- 0.05mm    

Pull Strength: 1.83kg
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 1mm thickness The axis through which a product is magnetised.   



Gauss: 439
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).   

Features:
- Powerful Rare Earth (Neodymium) permanent magnet.
- High gloss Nickel coating, for protection against corrosion.
- Maximum operating temperature 80°C / 100°C
