What is the Mega Gauss Oersteds (MGOe)?

Mega Gauss Oersteds is the CGS measure for the maximum energy product of a magnet (BHmax).
The five main types of magnetic materials have the following typical maximum energy products:

• Neodymium up to 52 MGOe
• Alnico up to 5.5 MGOe
• Ferrite up to 3.5 MGOe
• Samarium Cobalt up to 32 MGOe
• Flexible magnets up to 2 MGOe
