What is Maximum Energy Product / (BH)max and How Does It Correspond to Magnet Grade?

The term Maximum Energy Product ((BH)max) is a commonly used, but often misunderstood figure of merit of magnets. The (BH)max is an Energy Density and it is oftentimes used to denote grade. The grade convention is especially used for Rare Earth magnets, (Neodymium Iron Boron Magnets and Samarium Cobalt Magnets). For instance, a grade 48 Neodymium Iron Boron magnet will generally have an advertised (BH)max of 48 MGOe
