WebSep 12, 2024 · Steel is an iron alloy that comes in many forms, with a correspondingly broad range of permeabilites. Electrical steel, commonly used in electrical machinery and … WebThe permeability of ferromagnetic materials is not constant, but depends on H. In saturable materials the relative permeability increases with H to a maximum, then as it approaches saturation inverts and decreases toward one. [2] [3] Different materials have different saturation levels.
