Electrical Engineering ⇒ Topic : Absolute permeability

Absolute permeability (μ). It is the ratio of flux density in that material to the magnetising force producing that flux density and is denoted by ; μ , μ = μ₀  μ_r,.; where μ₀, is the permeability of free space having i value of 4π  x 10^-7 H/rn.
