ABSOLUTE PERMEABILITY

Definition: The Absolute Permeability (𝜇ₐ) is the ratio of the flux density B (in webers/sq meter) in a substance to the field intensity or magnetizing force H (in newtons/weber of ampere turns/meter) which produces that flux density B.

i.e.,                                                     μa=BH

The Absolute Permeability  𝜇ₐ is also related to the 𝜇₀ (free space) and 𝜇ᵣ (relative permeability) as:

μa=μ0×μr
