Anisotropic Ferrite Magnet Specifications
The magnetic properties of the material are standardized for performance in each grade. These values are obtained from the inspection and measurement of a base material sample (shape ratio: height/diameter = 0.7) before cutting, using a BH analyzer. The magnetic properties of magnets that have been cut from the base material to final dimensions depend on the shape ratio and environmental temperature. The information in this catalog is subject to change without notice due to improvements or other reasons.
