BH Curves for Neodymium Magnets

Graphs and info about demagnetization (BH) curves and hysteresis loops

What is a BH curve?

A BH curve, also known as 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.
