A second quadrant demagnetization curve provides information about the magnetic characteristics of a magnet, including the magnetic field strength and how resistant it is to demagnetize. How it is used in a magnetic circuit will affect its performance. When a permanent magnet is fully magnetized, its magnetic domains are aligned. Certain conditions such as temperature and reverse magnetic fields can cause some of the domains to lose this alignment and reverse, triggering the magnet to lose some or all of its magnetic field.

Adams Stock Products Catalog 2018
We are delighted to share our 2018 catalog with you. We’ve added updated information about our fabrication capabilities, available in Elmhurst, IL and Carlsbad, CA. We’ve also added new neodymium holding assemblies, a MAGbond Magnetic Media System overview, and high energy wide-format magnetic sheet (40″ wide and still printable!). If you’d prefer to receive a hard copy of this catalog, let us know.
Adams Hard Magnet Materials Catalog updated 2020
(7MB) This PDF catalog features a magnet materials overview, chart of materials properties and demagnetization curves for Neodymium, Samarium Cobalt, Ceramic (Ferrite) and Alnico materials offered by Adams. New in 2020, we’ve added more curves, and a coatings chart to assist with corrosion protection decisions.
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.
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.
Samarium Cobalt Product Specifications
Samarium Cobalt (or SmCo) magnets are strong permanent magnets made of an alloy of samarium and cobalt. They are known for their high magnetic strength, exceptional temperature resistance, and reliable performance without oxidation protection. As a result, they are more suitable for certain applications than Neodymium magnets.
