magnetic permeability, English name: magnetic permeability, characterizing the physical quantity of magnetic media. Represents the resistance of a coil in space or in the space of a magnetic core to create a magnetic flux or its ability to conduct a field line in a magnetic field. The formula μ=B\/H, where H= magnetic field strength, B= magnetic induction strength, commonly used symbol μ, μ is the permeability of the medium, or absolute permeability.
There is no such thing as DC permeability and AC permeability.
