Neodymium magnets Specification of magnetic properties

Performances of magnetic properties of material are standardized based on grades. These are figures taken by measuring base specimen material with a BH analyzer (form ratio: height/diameter =0.7). After cutting the base material, the final magnetic properties will differ to these figures since they depend on the form ratio and environmental temperature. The information provided may change without prior notice due to improvements etc.
