For instance, a grade 48 Neodymium Iron Boron magnet will generally have an advertised (BH)max of 48 MGOe. (The unit MGOe, Gauss•Oerstedx10^6, or Mega-Gauss•Oersted is used in the CGS (Centimeter-Gram-Second) unit system A magnet grade is a good measure of the strength of a magnet. In general, higher numbers indicate a stronger magnet. The number comes from an actual material property, the Maximum Energy Product of the magnet material, expressed in MGOe (Mega Gauss Oersteds). It represents the strongest point on the magnet's Demagnetization Curve, or BH Curve MgOe stands for Megagauss Oersteds and indicates how much energy a piece of magnet material can supply to a circuit. IMI's UHI-50 is the most powerful circuit available in the marketplace, featuring greater pull-test strength and holding value than any other circuit
Neodymium magnets will lose about 1% of their magnetic strength every 10 years due to self demagnetization. BHMax (MGOe) - Maximum Energy Product Measured in Mega Gauss Oersteds This is a direct measurement of a materials maximum magnetic strength after the magnet is fully saturated charged by an external magnetic field Neodymium magnets produce the highest MGOe of any permanent magnet material. The most common grades of Neodymium magnets are N35, N38, N40, N42, N45, N48, N50, N52, and N55. For Samarium Cobalt (SmCo) Magnets, the BHmax will range from 16 MGOe to 32 MGOe. Again, like neodymium magnets, the higher the number, the stronger the magnet The maximum energy product of a magnet is measured in Mega Gauss Oersteds (MGOe).This is the primary indicator of a magnets 'strength'. In general, the higher the maximum energy product value, the greater the magnetic field the magnet will generate in a particular application. Maximum energy product, also referred to as BHmax is calculated. An N42 magnet has a maximum energy product of 42 MGOe, while an N52 magnet has a maximum energy product of 52 MGOe. When comparing neodymium magnets, we find that the pull force relates directly to this number. If everything else is equal, a magnet with a BHmax that's 10% higher will have about a 10% higher pull force

Like neodymium iron boron, samarium cobalt is a rare earth material available in both sintered and bonded forms. The two materials share many attributes, including High Br, high Hc, relatively high BHmax (approximately 18-33 MGOe), high resistance to demagnetization, low machinability, and suitability for multiple pole magnetization given the proper magnetizing.
The oersted is defined as a dyne per unit pole. The oersted is 1000/4π (≈79.5774715) amperes per meter, in terms of SI units. The H-field strength inside a long solenoid wound with 79.58 turns per meter of a wire carrying 1 A is approximately 1 oersted. The preceding statement is exactly correct if the solenoid considered is infinite in. An alloy composed of aluminum, nickel, and cobalt, alnico magnets have been popular since the 1930s.
