(7MB) Featuring a magnet materials overview, chart of materials properties and demagnetization curves for Neodymium, Samarium Cobalt, Ceramic (Ferrite) and Alnico materials offered by Adams.
Standard Specifications for Permanent Magnet Materials
Defines thermal and mechanical characteristics and properties of commercially available permanent magnet materials including Alnico, Ceramic, Rare Earth (Samarium cobalt and neodymium) and Iron-Chromium-Cobalt. Includes a Glossary of Terms and Magnetic Quantities (Symbols, Units and Conversion Factors).
Breakaway Force of a Magnet
Explains the test methods used to determine how much force it takes to pull a magnet directly away from the surface it is attached to.
Chart of Material Properties
Displays each permanent magnet material along with its Maximum Energy Product: Bhmax, Residual Flux Density: Br Gauss, Coercive Force: Hc Oersteds, Intrinsic Coercive Force: Hci Oersteds and Maximum Operating Temperature: C / F.
