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. Products may be magnetised axially, diametrically or otherwise (e.g. multipole).
Gauss: 318 Gauss
A measurement of surface “magnetic induction” (B), equal to one ten-thoudansth of a Tesla. Gauss indicates the number of lines of magnetic flux per square contimetre, under the CGS metric system.
Grade: N35
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:
Our quality assurance system in factory meets the requirements of ISO9001:2008 as certified by Universal Certification Service Co., Ltd. (Short as UCS) Our products meet RoHS standard as per test reports issued by an internationally recognized laboratory SGS.
-Powerful Rare Earth (Neodymium) permanent magnet
-High gloss Nickel coating, for protection against corrosion
-Maximum operating temperature 80℃/100℃
Application:
These large discs are incredibly strong and are great for science and levitation experiments, but must be handled very carefully. They can pinch quite hard and will most likely break if two are allowed to slam together. Always use caution when working with magnets of this size.
