One MGOe is 1,000,000 Gauss Obersted. A grade forty (N40) would have a Maximum Energy Product of 40 MGOe.The higher the grade the “stronger” the magnet. Disc Neodymium Magnet N38 Ni
Magnetic materials have a wide range of working temperatures. The following chart the various materials and their maximum working temperature. NdFeB material comes in many different heat tolerances but as the heat tolerance increases the maximum available fulx density decreases:
Description Magnet

Woking Temperature Grade Max.Operating Temperature
N35-N52 80°c
33M-48M 100°c
33H-48H 120°c
30SH-45SH 150°c
30UH-40UH 180°c
28EH-38EH 200°c
28AH-35AH 220°c
