Neo magnets are also called Neodymium magnets, Rare Earth magnets, Nd-Fe-B magnets, Neodymium Iron Boron magnets or NIB magnets. They are a permanent magnet made from an alloy of neodymium, iron and boron. Neodymium magnets have grades from N35 to N52 and are the strongest and cost effective permenant magnets manufactured.

The energy product is specified in units of Gauss Oersted. One MGOe is 1,000,000 Gauss Oersted. A grade N45 would have a Maximum Energy Product of 45 MGOe. The higher the grade the stronger the magnet.
