BHₘₐₓ (Maximum Energy Product) indicates the maximum energy density of a magnet. It’s measured in Mega Gauss Oersteds (MGOe) and directly correlates to the strength of the magnet. Higher BHₘₐₓ values mean a stronger and more efficient magnet.

Each magnetic material has a temperature coefficient that defines how its magnetic strength changes with temperature.

Magnetic anisotropy refers to a material's directional dependence of magnetic properties.
