200mm x 25mm Disc - N42 (Rare Earth, North Pole Dent)

Please note: This is an extremely strong magnet and extreme care must be taken when handling. In order to be transported it must be packaged inside a very large carton to contain the magnetic field. Express post is not available.

Dimensions: Ø  200mm (Diameter) x  25mm (Height)  
The dimensions of the product are measured in metric units, with an approximate "tolerance" (manufacturing margin of error) of +/- 0.05mm

Pull Strength: This magnet is too large to accurately calculate strength. It will exceed 850kg of pull strength.
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 25mm height. The axis through which a product is magnetised. 

Gauss: Unavailable
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
