Demagnetization (BH) Curves for Neodymium Magnets

What is a demagnetization curve?

A demagnetization curve describes the magnetic qualities of a magnet more completely than a single number like Pull Force or Surface Field. It provides information about the strength of the magnet, how hard it is to demagnetize, and how a magnet's shape (or use in a magnetic circuit) affects matters.
